Sift features matlab
WebSIFT feature descriptor will be a vector of 128 element (16 blocks \(\times\) 8 values from each block) Feature matching. The basic idea of feature matching is to calculate the sum square difference between two different feature descriptors (SSD). So feature will be matched with another with minimum SSD value. \[SSD = \sum (v_1 - v_2)^2\] WebMay 2, 2015 · SIFT Feature Extreaction.
