Lines recognition in opencv

Hello everybody.

I have a problem where I need to recognize some lines inside a bmp image.

I am able to get some matches from the image and I am trying to reject the bad matches.

For example I have to reject this match:

while I have to accept this match:

I am not looking for the solution, I just want to ask if there is or not some method to check if a set of points is an approximation of a line, or if there is some method/algorithm that can be useful to solve my problem.

Thank you for any advice ;)

Looks difficult, since you don't have real clear edges. But anyways you could at least try the algorithms which are part of OpenCV, e.g. HoughLines (and the probabilistic version HoughLinesP), see: http://docs.opencv.org/modules/imgproc/doc/feature_detection.html?highlight=hough#houghlines and in the current trunk another Method named "LSD" exists: http://docs.opencv.org/trunk/modules/imgproc/doc/feature_detection.html?highlight=lsd#linesegmentdetector .

Good Luck!
