About this document

Feature Extraction Techniques Analysis by IJERD is a document available to read on EtoBox.

This document summarizes and compares various feature extraction techniques in both the spatial and transformed domains. In the spatial domain, it discusses traditional methods like Canny edge detection as well as the scale invariant feature transform (SIFT) developed by David Lowe. SIFT detects local features in an image and is invariant to changes in scale, rotation, and illumination. The document also examines variants of SIFT such as PCA-SIFT, ASIFT, A2SIFT, and SURF, which improve on SIFT
