Critical examination of the slanted-edge method for color SFR measurement reveals inaccuracies in the estimated SFR, due to the use of demosaicing.
The proposed method resolves these inaccuracies by eliminating the need for demosaicing during SFR measurement.
Please download CFASFR.zip, and run the MATLAB script driver_CFASFR.m to see the algorithm in action.
For instructions on using the proposed SFR estimation algorithm with your images, please examine README.txt in the same ZIP file.
