# remap: how to find the (x,y) in dst given (u,v) in src? [closed]

remap function can give you the point (u,v) in the src image when you have point (x,y) in dst image through the map1 and map2 mapping function. I do not know if I have the input (u,v) in the src image, how can I get the corresponding point (x,y) in the dst image??
