Can I use OpenCV for Leaf Matching project

edit

Thanks for replying .I went through the link but method which i see are in C,C++,python and I am using java-android .I was also confused which method should be use for calculating the below parameters. 1)Centroid-contour Distance Curve 2)bounding rectangle 3)region-of-interest (ROI) area 4)convex hull area (A C ) 5)ROI perimeter (P ROI ) 6)convex hull perimeter (P C ) 7)Regional Moments of Inertia 8)Angle Code Histogram

http://docs.opencv.org/trunk/doc/py_t... may give you hints on computing some of your features. Nearly all the functionality of OpenCV is also wrapped for Java, so just use the corresponding java-function (see http://docs.opencv.org/java/ )
