Feature extraction is a type of dimensionality reduction where a large number of pixels of the image are efficiently represented in such a way that interesting parts of the image are captured effectively .
Read moreHow does feature extraction work?
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.10 Eki 2019

Feature extraction is a part of the dimensionality reduction process, in which, an initial set of the raw data is divided and reduced to more manageable groups . So when you want to process it will be easier.29 Eki 2021
