ou can get all the details about the problem from this pdf document: www.shaastra.org/2013/media/events/70/Tab/422/Modern_Warfare_ps_v1.pdf

how to recognize a zebra crossing from top view using opencv ?? it is not a straight zebra crossing it has some twists and turns i have some ideas, 1. parallel line detection but the available techniques only works to find straight parallel not the ones that has curve in it. 2. template matching to match a template of back to back white and black stripes but it becomes tedious since i cant find any pattern matching techniques with scaling and rotation.

in fact a idea on any single part of the problem will be so helpful! it is driving me crazy someone please help!!!! any help is appreciated thanks in advance ....
