Thanks for contributing an answer to Stack Overflow! IV. GoogLeNet has been trained on over a million images and can classify images into 1000 object categories (such as keyboard, coffee mug, pencil, and many animals). Each anchor box is used to produce a ROI (Region of Interest) where EmguCV can be used to crop the original image to produce another image which is scaled to the same dimensions of original image. Its practically what you need currently. Load the pretrained GoogLeNet network. As convolution of image using appropriate kernel extracts certain features from the image and then the rectified linear activation function eliminates negative values and then finally a pooling layer decreases the dimensions of the output while preserving important features, it is well fit to extract proper features that define a classification, however abstract it might be, like the difference between a dog and a cat. The length of the output array is the same as the number of output neurons in the network.
