Vedaldi's MATLAB Implementation of D.G. Lowe's SIFT Algorithm

This upload contains Vedaldi's MATLAB implementation of D.G. Lowe's SIFT algorithm. Although similar source code exists online, this attached code has been specifically compiled, tested, and verified to run directly without modifications. A critical bug in sift.m has been identified and fixed (with notification sent to Mr. Vedaldi), ensuring reliable feature extraction performance.
