I have a process where I am matching one template image in the main image and its running correct , but when i run the same process on a remote desktop the image matching is not happening , the maxVal is coming less in the later case.

compression. if you expect perfect numbers, compression has to be lossless. remote desktop programs commonly use lossy compression. you have to be able to deal with non-perfect matches.

also maybe the remote image is displayed scaled down. you also have to make sure you get the same scale your template is from.
