A Comprehensive Guide to Convolution Neural Network

As we saw in the structure of CNN, convolution layers is used to extract the features and for extracting features it uses filters. So, let us discuss about how the features are extracted using filter now. In the above image we used various filters like Prewitt or Sobel and obtained the edges. For detail understanding about working on the images and extracting edges you can shoot up at my below blog for theoretical and practical implementation. Let us understand how filter operation basically works using an animated image.
