Resource Overview
This project implements SIFT (Scale-Invariant Feature Transform) feature extraction for images, containing comprehensive usage documentation and ready-to-run compiled versions. The source code is available in both Matlab and C implementations, delivering robust feature detection performance with good practical results.
Detailed Documentation
The documentation provides guidance on achieving optimal results through SIFT feature extraction from images. You can compile and run either the Matlab version (utilizing built-in image processing toolbox functions) or the C language implementation (optimized for performance with manual memory management). Both versions implement the standard SIFT algorithm workflow including keypoint detection, orientation assignment, and descriptor generation. The Matlab version offers easier prototyping with high-level functions, while the C version provides better computational efficiency for production environments. Regardless of your chosen implementation, both versions demonstrate reliable feature extraction capabilities suitable for computer vision applications.
