This example shows how to extract learned features from a pretrained convolutional neural network, and use those features to train an image classifier. Feature extraction is the easiest and fastest way use the representational power of pretrained deep networks. For example, you can train a support vector machine (SVM) using |fitcecoc| (Statistics and Machine Learning Toolbox(TM)) on the extracted features.
