Matching Descriptors using Fast Approximate Nearest Neighbor
matches=cv_flannmatch(des1,des2,num_trees,numchecks,k)
Decriptors Obtained from one image
Descriptors Obtained from second Image
Number of trees that must be used-> must be constant
Number of checks to be performed -> MUst be a constant
must be a constant
The function returns the number of matched features
Mathing Descriptors
This function Matches descriptors of two images using Fast Approximate Nearest Neighbor Algorithm
