Using MSER region and improve results

edit

Hi, I start using MSER region in video and results seems are not stable. This video is a room made by a webcam logitech h270 (with noise). I have made three differents experience :

1 convert image to grayscale looking for ORB features (red circles) and MSER region in red results

2 convert image to grayscale calculated scharr gradient and looking for ORB features and MSER region results

3 convert image to grayscale blur image calculated scharr gradient and looking for ORB features and MSER region results

I have tried to modify some parameters and I don't find goods one to have region stable in surface. ORB features seems to be more accurate for tracking than MSER. If somebodycan give me idea about parameter in MSER I would appreciate.

Thanks
