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 moreWhat means feature extraction?
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
Read moreWhat is feature extraction from image?
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
