O(1) contrast preserving decolorization using linear local mapping. Abstract: We propose an effective and efficient local decolorization method in this paper.
The proposed method exploits the gradient-based correlation similarity approach, in which global and local contrast information is considered for a total of ...
In local mapping methods, the same color pixel within an image could be mapped into different grayscale values depending on its spatial location. ... ... Most ...
