Color to Grayscale Conversion with Chrominance Contrast
نویسنده
چکیده
Color information is usually discarded when converting a color image into a grayscale image. However, it is sometimes desirable to reflect chrominance change where luminance contrast is not obvious. Inspired by tone mapping technique, this paper proposes a similar method for color to grayscale conversion, which in addition takes into account the local chrominance changes. The result shows great improvement in efficiency over recently proposed global optimization techniques.

Significance of perceptually relevant image decolorization for scene classification
A color image contains luminance and chrominance components representing the intensity and color information respectively. The objective of the work presented in this paper is to show the significance of incorporating the chrominance information for the task of scene classification. An improved color-to-grayscale image conversion algorithm by effectively incorporating the chrominance informatio...
متن کاملGlobal Color Saliency Preserving Decolorization
The process of transforming a color image with three channels to a single channel grayscale image is called decolorization, which will unavoidably accompany with the information loss. In this paper, we propose a method to obtain a grayscale image which best preserves the global saliency of the color image. First, we convert the color image to the YUV color space, which separates the luminance a...
متن کاملSpatial Color-to-Grayscale Transform Preserving Chrominance Edge Information
A color image sent to a monochrome output device must undergo a color-to-grayscale transformation. Such a transform typically retains the luminance channel or a derivative thereof. A problem with this approach is that the distinction between two different colors of similar luminance is lost. This loss can be particularly objectionable if the two colors are spatially adjacent. The paper describe...

متن کاملColor to Grayscale Conversion Based On Neighborhood Pixels Effect Approach for Digital Image
Conventional color to grayscale conversion algorithms cannot perform well in certain circumstances and the resultant grayscale images produced have low contrast and interpretability. Thus, we propose a new adaptive approach to overcome the drawback, namely the neighborhood pixels effect approach. In this approach two algorithms are proposed under this approach, namely the Neighborhood Effect Co...
