Before getting features, various image preprocessing techniques like binarization, thresholding, resizing, normalization etc. are applied on the sampled image. After that, feature extraction techniques are applied to get features that will be useful in classifying and recognition of images.
Read moreHow do you extract a feature from a dataset?
Feature Extraction aims to reduce the number of features in a dataset by creating new features from the existing ones (and then discarding the original features) . These new reduced set of features should then be able to summarize most of the information contained in the original set of features.
