[@datascienceandmachinelearn2537]

Hei Murtaza, I need an advice fo my bachelor project. I follow your amazing course,please help me as your loyal follower. I will create an obscure view detection model that detects the loss of vision in cameras of autonomous vehicles caused by fog, condensation, and blaze, especially for sea vehicles. Can you suggest a model, thesis, article, dataset on this subject, please?

[@shrijanmaram7939]

Hi sir, why my program doesn't open the image? Is it because I'm using a mac?

[@murtazasworkshop]

This should work with mac as well. make sure your image is in the same folder as your script file.

[@sanjaybalasubramanian9468]

Please use white theme for tutorials

[@prilaogniler2790]

Thank you for this Sir.By the way Sir can you help about this error that I've encounter. Thanks :)
Traceback (most recent call last):

[@murtazasworkshop]

It seems your img is empty . if you will print out img using print(img) it will show you NONE. This means the import of the image has failed .
To solve this check your path of the image . if its in the main directory . use
img = cv2.imread(''imageName.jpg'').
If the problem is still there . Share your code and i will have a look .

[@prilaogniler2790]

@@murtazasworkshop Hi Sir. Here's the code same as your code I just change the image filename.
import cv2
path = "Resources/lion1.jpg"
img = cv2.imread("lion1.jpg") --------I change it but I encounter the same problem.
print(img.shape)
width ,height = 1000 , 1000
imgResize = cv2.resize(img,(width,height))
print(imgResize.shape)
imgCropped = img[300:540,430:480]
imgCropResize = cv2.resize(imgCropped,(img.shape[1],img.shape[0]))
cv2.imshow("Lion1",img)
cv2.imshow("Lion1 Resized",imgResize)
cv2.imshow("Lion1 Cropped",imgCropped)
cv2.imshow("Lion1 Cropped Resized",imgCropResize)
cv2.waitKey(0)

@@prilaogniler2790 your image might be png. Share a screen shot of ur directories if the problem stays . I will have a look.
