Captures spatial arrangements of pixel intensities. Identify keypoints that are often invariant to scale,
Feature extraction is a fundamental process in computer vision that transforms raw pixel data into a structured set of characteristics (feature vectors) that computers can easily interpret. By distilling the essence of an image into these numerical representations, it reduces dimensionality and computational cost while preserving vital information for tasks like object recognition, classification, and image matching .

Feature extraction can be broadly categorized into traditional "handcrafted" methods and modern automated deep learning approaches.
A faster, more efficient alternative to SIFT.
Identifies boundaries within an image where intensity changes significantly.
