This MATLAB code is the feature extraction by using SIFT algorithm. Just download the code and run. Then you can get the feature and the descriptor. Note, If you want to make more adaptive result. Please change the factories: row, column, level, threshold., and d(in the last part). For other factories, please do not change until you understand David G. Lowe's paper and my code.
