Hi,
I have a difficulties while trying to match the image of leafs. In fact it's the image of a single leaf taken on different dates, so the angle, size and illumination is a little different on each photo. In the meantime the leaf can deform a little (growing).
I try to match the leafs using keypoints. The SIFT/SURF detector give quite evenly placed keypoints, but the matcher (BF of Flann) can't match them (see image below). The code I'm using is very similar to this tutorial
Do you have any other ideas to detect keypoints on the leafs and match them?
Here are some images I'm working with: IMAGES. I already eliminated most of the background (value 0) except some isolated pixels) and most of the differences of illumination.
I'll appreciate any ideas!!
