I just find out the contours in the image using find contour function.It shows output like the below image. image description . Now I need to group the nearby contours in the zebra-crossing lines to get full area.How this can be done?

try blurring your image , kmeans with 2 clusters will somewhat combines all the zebra-crossing line and then apply findcontours. it might not be the good approach but it might work
