Images Matching and Stitching Based on PCA-PSO

Traditional images matching usually got some wrong matchers, which mean need to improve.First of all, get the 128-D descriptors according to SIFT, Make the dimensions less by using PCA and then find the best matchers by using PSO and finally start to stitch. Contrast to the traditional matching method and the images matching method based on PCA, the algorithm in this paper proved to be more accurate and it makes the following stitching better as well.
