After using MSER as feature detection algorithm and SURF as descriptor extractor algorithm, i got the below image and i think it represents false matchings. please have alook at the picture and notice the green lines and the pink one. these lines are linked to different features, because i assume that these lines produced from the matching process should be linked to the same features.

please let me know why i am getting false matches and how to solve this issue

Note:

I used also ORB algorithm as for feature detection and descriptor extractor and i received the first image posted below without aplying any geometric transformation/correction using RANSAC.

does it means that ORB algorithm does not require applying RANSAC?
