WebThe frequencies of the key point allocations are recorded over the code words to generate the BoVW vector. In the last step, the labelled BoVW vectors are used to train the image classifier using ... WebBOW = cv.BOWKMeansTrainer (dictionarySize) I have 80 training images. So, I add the descriptors of each image to BOW like: kp,desc=surf (img) BOW.add (desc) All of these form a dictionary with size (20,64). What does this 64 mean? And, how does the BOW trainer know that some image x belongs to class c? What data do I feed into the SVM?
