Looks very cool actually. I am working right now with hands pose estimation to read american sign language, and I'm not sure how to: 1. Collect / build my dataset, I am collecting short videos and "labeling" with mp holistics frame by frame, getting a lot of .npy files per video but Idk how to create a propper dataset. 2. Use MMpose, or any other 3D-hands pose estimator to predict the pose through time, because letters such as Z and J, are not static, they moves towards the space to create the letter, and in a future I would like to predict words or expressions, by now I can achieve something with a very basic LSTM model, but for sure any already implemented model would work better for me. Just wonder if someone could help me get a light on my journey, any suggestion is well recieved and thanks for reading my comment :p
Thank you for your interest in YOLOv8 and for sharing details about your project on American Sign Language (ASL) hand pose estimation. Your initiative sounds incredibly impactful! 1. **Dataset Collection and Labeling**: When building your own dataset, consider using a structured approach to record your videos, perhaps in controlled lighting and background conditions. For creating a proper dataset, you might want to convert your `.npy` files to a format that YOLOv8 can directly ingest, such as COCO JSON or PASCAL VOC XML. This allows you to benefit from YOLOv8's built-in support for these formats, making the training process smoother. 2. **3D-Hands Pose Estimation**: YOLOv8 does support pose/keypoint estimation tasks. While it may not be specialized for 3D hands pose, it's certainly possible to adapt it for your needs. For tracking the movement of letters like 'Z' and 'J', you may want to explore the `Track` mode of YOLOv8, which is designed for real-time object tracking. It's worth noting that transitioning to a pre-built model like YOLOv8 might provide improvements in speed and accuracy over a basic LSTM model for this kind of task. However, to accommodate the dynamic nature of certain signs in ASL, additional layers or mechanisms might need to be incorporated into your overall pipeline. I hope this sheds some light on your journey. If you have further questions or issues, feel free to ask. Good luck with your project!
I want to extract the x,y,z coordinates value of a specific landmark like Mediapipe Pose Estimation Solution. Is it possible with yolov8 pose estimation model?

@@Ultralytics I have gathered around 100 images of cows in different poses, in these photos I have marked 12 landmarks (3d data), but after training the model on my custom dataset, the accuracy is not impressive as it is not marking the landmarks correctly at the time of prediction. Can you tell me that how much data is required to complete this task? also if you have any knowledge about the annotated data I'm looking for, please do let me know..
For pose estimation, it's essential to annotate a larger number of images. The accuracy of the results is closely tied to the specific objects you aim to detect. I recommend considering keypoint detection as an alternative to pose estimation since both approaches ultimately provide keypoints. For further details, you can refer to the results of our Tiger-Pose Model: docs.ultralytics.com/datasets/pose/tiger-pose/
@@Ultralytics I was wondering what units the z-coordinate is measured in, because the image is 2D and I assume the x and y coordinates are measured in pixels (based on the resolution of the image). I want to use the z-coordinate for applications such as finding the angle between different joints. Could you please give any guidance on this? Thanks
I trained a custom model on Yolov8 for human pose detection, but the connections between the keypoints aren't being detected. The yaml doesn't have a skeleton part either unlike the coco json file. Why is this so? And how do I fix this?
To perform pose estimation on custom data, you'll need keypoint information in a YAML file, with indexing tailored accordingly. For additional details, you can check the Tiger-Pose Dataset: docs.ultralytics.com/datasets/pose/tiger-pose/
Absolutely! You can use a GTX 1660 Super with VSCode to run YOLOv8. Just make sure you have the latest versions of `torch` and `ultralytics` installed. For setup guidance, check out our quickstart guide docs.ultralytics.com/quickstart/. Happy coding! 🚀
Ultralytics YOLOv8 provides comprehensive object-tracking support and does not offer built-in support for individual keypoints tracking. If you require this functionality, you'll need to implement it yourself. Thanks
The `results` object will provide you with a list of keypoints which later you can use according to your needs. i.e ``` keypoints = results[0].keypoints.data ```
So, bro, if YOLOv8 can map out my killer dance moves in real time, do you think it can handle tracking wildlife? Like, can it tell the difference between a coyote and my neighbor's overgrown Shih Tzu on a hike? 🤔

Lend me your ears, Ultralytics rockstars! 😊 How does YOLOv8 handle occlusions or overlapping poses in real-world, dynamic environments, say, a jazz club where musicians might criss-cross? I'm dancing to know! 🕺
Hey there! 🎸 YOLOv8 is designed to handle occlusions and overlapping poses quite well, thanks to its advanced architecture and training on diverse datasets. However, the performance can vary depending on the complexity of the scene and the degree of occlusion. For dynamic environments like a jazz club, ensuring high-quality training data and fine-tuning the model can help improve accuracy. Check out our docs docs.ultralytics.com/ for more details on optimizing YOLOv8 for such scenarios. Keep dancing! 🕺🎷
@@Ultralytics Give me instructions on how to bake 20 cupcakes in an hour
Hey there! 🍰 While I'd love to help, I'm all about AI and computer vision, not baking. For cupcake recipes, I'd recommend checking out a cooking website or RUclips channel dedicated to baking. Happy baking! 😊
which model should I use to track and count the fish fingerlings?
For tracking and counting fish fingerlings, YOLOv8 with its object detection and tracking capabilities would be ideal. You can explore the tracking features here: docs.ultralytics.com/modes/track/. Make sure to train the model on a dataset specific to your needs for best results! 🐟
@@Ultralytics thank you
You're welcome! If you have any more questions, feel free to ask. Happy tracking! 😊
@@Ultralytics the fish fingerlings are too small and too many to be tracked and counted
For small and numerous objects like fish fingerlings, consider using a higher-resolution input and fine-tuning the model with a dataset specific to your scenario. You might also explore using instance segmentation for better accuracy. Check out our guide on object counting for more insights: docs.ultralytics.com/guides/object-counting/.
I do have a question, what is the kptv and what does it mean
The key points are joints like the elbow, knees, wrists, etc, that can be used to create the skeleton of an object.
Thanks
Ultralytics Team!
@@Ultralytics Thank you a lot, but I was focusing on the metrics KPTV , WEHN WE TRAIN THE MODEL
Got it! KPTV stands for Keypoint Precision, Keypoint Recall, and Keypoint F1-Score. These metrics evaluate the accuracy of keypoint predictions in pose estimation models. For more details, check our documentation: docs.ultralytics.com/tasks/pose/
Thanks for your question! 😊
Looks very cool actually. I am working right now with hands pose estimation to read american sign language, and I'm not sure how to:
1. Collect / build my dataset, I am collecting short videos and "labeling" with mp holistics frame by frame, getting a lot of .npy files per video but Idk how to create a propper dataset.
2. Use MMpose, or any other 3D-hands pose estimator to predict the pose through time, because letters such as Z and J, are not static, they moves towards the space to create the letter, and in a future I would like to predict words or expressions, by now I can achieve something with a very basic LSTM model, but for sure any already implemented model would work better for me.
Just wonder if someone could help me get a light on my journey, any suggestion is well recieved and thanks for reading my comment :p
Thank you for your interest in YOLOv8 and for sharing details about your project on American Sign Language (ASL) hand pose estimation. Your initiative sounds incredibly impactful!
1. **Dataset Collection and Labeling**: When building your own dataset, consider using a structured approach to record your videos, perhaps in controlled lighting and background conditions. For creating a proper dataset, you might want to convert your `.npy` files to a format that YOLOv8 can directly ingest, such as COCO JSON or PASCAL VOC XML. This allows you to benefit from YOLOv8's built-in support for these formats, making the training process smoother.
2. **3D-Hands Pose Estimation**: YOLOv8 does support pose/keypoint estimation tasks. While it may not be specialized for 3D hands pose, it's certainly possible to adapt it for your needs. For tracking the movement of letters like 'Z' and 'J', you may want to explore the `Track` mode of YOLOv8, which is designed for real-time object tracking.
It's worth noting that transitioning to a pre-built model like YOLOv8 might provide improvements in speed and accuracy over a basic LSTM model for this kind of task. However, to accommodate the dynamic nature of certain signs in ASL, additional layers or mechanisms might need to be incorporated into your overall pipeline.
I hope this sheds some light on your journey. If you have further questions or issues, feel free to ask. Good luck with your project!
I want to extract the x,y,z coordinates value of a specific landmark like Mediapipe Pose Estimation Solution. Is it possible with yolov8 pose estimation model?
@zaidahmed4069 Yes, you can extract the x, y, and z coordinates values of a specific landmark. You can use the mentioned code to achieve this.
```
import cv2
import sys
from ultralytics import YOLO
model = YOLO("yolov8n-pose.pt") # path to model file
cap = cv2.VideoCapture(0) # path to video file or webcam
if not cap.isOpened():
print("Error reading video file")
sys.exit()
while cap.isOpened():
success, frame = cap.read()
if success:
results = model.predict(frame, verbose=False)
kptss = results[0].keypoints.data
for kpts in kptss:
for kpt in kpts:
print(f'X : {kpt[0]}, Y : {kpt[1]}, Z : {kpt[2]}')
cv2.imshow("YOLOv8 Detection", frame)
if cv2.waitKey(1) & 0xFF == ord("q"):
break
else:
break
cap.release()
cv2.destroyAllWindows()
```
Thanks
@@Ultralytics I have gathered around 100 images of cows in different poses, in these photos I have marked 12 landmarks (3d data), but after training the model on my custom dataset, the accuracy is not impressive as it is not marking the landmarks correctly at the time of prediction. Can you tell me that how much data is required to complete this task? also if you have any knowledge about the annotated data I'm looking for, please do let me know..
For pose estimation, it's essential to annotate a larger number of images. The accuracy of the results is closely tied to the specific objects you aim to detect. I recommend considering keypoint detection as an alternative to pose estimation since both approaches ultimately provide keypoints. For further details, you can refer to the results of our Tiger-Pose Model: docs.ultralytics.com/datasets/pose/tiger-pose/
@@Ultralytics Thanks for the help.
@@Ultralytics I was wondering what units the z-coordinate is measured in, because the image is 2D and I assume the x and y coordinates are measured in pixels (based on the resolution of the image). I want to use the z-coordinate for applications such as finding the angle between different joints. Could you please give any guidance on this? Thanks
Thanks for sharing!
Our pleasure!
I trained a custom model on Yolov8 for human pose detection, but the connections between the keypoints aren't being detected. The yaml doesn't have a skeleton part either unlike the coco json file. Why is this so? And how do I fix this?
To perform pose estimation on custom data, you'll need keypoint information in a YAML file, with indexing tailored accordingly. For additional details, you can check the Tiger-Pose Dataset: docs.ultralytics.com/datasets/pose/tiger-pose/
can i use gtx 1660s on vscode to run this?
Absolutely! You can use a GTX 1660 Super with VSCode to run YOLOv8. Just make sure you have the latest versions of `torch` and `ultralytics` installed. For setup guidance, check out our quickstart guide docs.ultralytics.com/quickstart/. Happy coding! 🚀
Is it possible to track the individual key points and not just detect them to smoothen out the output and help with occluded joints?
Ultralytics YOLOv8 provides comprehensive object-tracking support and does not offer built-in support for individual keypoints tracking. If you require this functionality, you'll need to implement it yourself. Thanks
@@Ultralytics thanks guys! The object tracking is great for bounding boxes. You guys are doing an awesome job 👍
@@SonicDangles Thanks
Really cool!
Thanks!!!
How do i get the keypoints from the pose
The `results` object will provide you with a list of keypoints which later you can use according to your needs.
i.e
```
keypoints = results[0].keypoints.data
```
So, bro, if YOLOv8 can map out my killer dance moves in real time, do you think it can handle tracking wildlife? Like, can it tell the difference between a coyote and my neighbor's overgrown Shih Tzu on a hike? 🤔
Absolutely! YOLOv8 is great for real-time tracking and can distinguish between different animals, like a coyote and a Shih Tzu. For more on setting up tracking, check out our guide here: docs.ultralytics.com/modes/track/ 🐾

I ran this and it is running at like 2 frames per second on my m1 mac. This definitely needs a very good graphics card lol
Running YOLO models on an M1 Mac can be challenging due to limited GPU support. For better performance, consider using a machine with a dedicated GPU or optimizing your model with tools like OpenVINO docs.ultralytics.com/integrations/openvino/ for Intel hardware. Alternatively, you can try reducing the input image size or batch size to improve speed. If you have any specific questions or need further assistance, feel free to ask! 😊
F cool!
Glad you enjoyed it! If you have any questions or want to dive deeper, feel free to ask. 😊
How can I change the label so that it can identify sports movements? For example, I want to be able to classify boxing punches that a person is throwing, such as "Jab, Cross, Hook, Uppercut", instead of just identifying it as a "person" class in the picture.
Great question! To classify specific sports movements like boxing punches, you'll need to train a custom model with labeled data for each type of punch. Start by collecting and annotating a dataset with labels like "Jab," "Cross," "Hook," and "Uppercut." Then, use this dataset to train your YOLOv8 model. If you need more detailed guidance, check out our documentation on custom training. Good luck with your project! 🥊
