Abstract
A method includes downsampling an input frame and performing global contrast enhancement of the input frame based on the downsampled input frame to generate a globally contrast-enhanced frame. The method also includes generating texture maps at different scale resolutions based on the downsampled input frame. The method further includes generating clipped histograms at the different scale resolutions based on the downsampled input frame. The method also includes generating lookup tables (LUTs) at the different scale resolutions based on the texture maps and the clipped histograms. The method further includes applying the LUTs at the different scale resolutions to the input frame in order to generate locally contrast-enhanced frames. In addition, the method includes blending the locally contrast-enhanced frames and the globally contrast-enhanced frame to generate an output frame.
