2017-12-22 06:11:14 -0600 | marked best answer | Lines detection Hi All, the following is a quite difficult task so any kind of help, even simple, will be much appreciated. After color segmentation I generated the following image I need to get lines that approximates white areas (roads), as shown in the following hand-made image Using probabilistic HoughLines with following parameters (image and lines are Mat instances): I get the following result: I tried several combinations of parameters and shown result seems to be the best that I can achieve. My questions:
