Here is the Comptuer Vision Course Project. It is the implementation of stitching several images into a panoramic image. There are basically two methods, one is mutual method, the other is automatic method.
To execute the mutual stitching, you just need to execute the file mutual_main.m in the folder code, and select 10 correspondences in a pair of images very carefully.
To execute the automatic stitching, basically you need to execute the file auto_main.m in the folder code. However, there are two main methods to implement the automatic stitching. You can modify the code in the file processImagePairs.m.
For example, in the following case, the program will use the RANSAC algorithm to compute the Homographic matrix rather than using the Gold Standard algorithm.
%H = computeHomoGold(p1, p2);
H = computeHomoRANSAC(p1, p2)
