    thank you for your videos... I am coming from a geospatial background.. I am using your channel to learn image segmentation and object detection for my project.. using deep learning to detect building damages along the shores after Hurricanes ... can you please do a video on how to use the xview2 dataset for image segmentation(buildings)

    how can we use Naive bayes for multi-class classification?

    • @DigitalSreeni

      Approach will be very similar to what I showed using Random Forest.
      Define your X and Y and split into train and test
      X_train, X_test, y_train, y_test = train_test_split(X, Y, test_size=0.25, random_state=0)
      from sklearn.naive_bayes import GaussianNB #Or other NB of your choice
      gnb = GaussianNB() #Instantiate the classifier
      y_pred = gnb.fit(X_train, y_train).predict(X_test) #fit the classifier.

    2:00 - What is that filter?

    • @DigitalSreeni

      It is a band pass filter. I believe I've used Joachim Walter's FFT Filter plugin in imageJ. It removes high spatial frequencies (blurring the image) and low spatial frequencies (similar to subtracting a blurred image). It can also suppress horizontal or vertical stripes that were created by scanning an image line by line.

    What filter did you use at 01:52 ?

      Sorry, not sure. Just added a bunch of filters and did not keep track of them. Looks like some sort of band pass filter.
