| 2014-01-16 01:26:45 -0600 | asked a question | OpenCV findContour() corners index order I am working with Android OpenCV .I have a square shape marker image .I have to find out the position of four corners of marker in the live feed with their index's position. I am able to get the position of these four points in the live feed having the frame size 640*480. But the problem with the index's positions those are not fixed ,sometimes i am getting the 0th index on the top left position and sometimes 1th index at that position ... How to solve this problem or is there any alternative for findContour() method. Your help will be appreciated... |
