… To quantitatively evaluate our decolorization algorithm in contrast-preserving, we have
conducted comparison experiments with the other five latest decolorization algorithms: [9], [11], …

… decolorization algorithms in terms of contrast preserving, we propose a new metric. It is based
on the finding that if the color … The task of contrastpreserving decolorization is therefore to …

… Contrast-Preserving Energy Function We describe in this section our new bimodal color contrast
preserving energy function with a weak color … for contrast preserving decolorization. The …

… We consider the classical energy used in the global adjustment approaches for contrast
preserving decolorization. The gray scales for pixels x and y are denoted by gx and gy …

… To quantitatively evaluate the decolorization algorithms in terms of contrast preserving, we
compute the Color Contrast Preserving Ratio (CCPR) in [9] for comparison in Table III, where …

… a novel parallel contrast-preserving decolorization algorithm. We relax the constraint of
color contrast with a new multimodal contrast-preserving measure for each color pair by further …

… Contrast-preserving decolorization based on feature descriptor introduces a simple cost
function. Moreover, the frequencies of the pixel pairs at M(x, y) and M(y, x) can be different. This …

… of the color contrast of the hazy image. Another intuitive way for the decolorization of a hazy
… a grayscale image using a current contrast-preserving decolorization algorithm such as [2]–[…

… Image decolorization known as the process to transform a color image to a grayscale …
decolorization is to preserve the color contrast of the color image. Traditional image decolorization …

… the decolorization algorithms in terms of contrast preserving, we compute the Color Contrast
Preserving … CCPR is based on the observation that if the color difference δ is smaller than a …
