ScreenshotMatcher

Proof of concept program to match photographs of computer screens with actual screenshots. Heavily based on OpenCV sample code for planar homography [1, 2].

Usage

OpenCV with contrib packages is required as the non-free SURF algorithm is used.

You might have to adjust the include path in the Makefile.

Execute the compiled program with parameters for an actual screenshot and the photograph of a subsection of this screenshot (scaled down to 512 px width seems to work better than original size):

./ScreenshotMatcher screenshot1_small.jpg org1.png

A new file (out.jpg) containing the cropped region of the screenshot will be created.
