Color transfer and image enhancement by using sorting pixels comparison

Fast color transfer is valuable in digital images. In this study, we devised a new algorithm called color transfer by using sorting pixels comparison. Firstly, according to color information, sort the pixel distribution separately on color images and grayscale images. Then, equalization is implemented on rearranged color images, appropriately weakens the proportion of the over bright and the over dark saturated zone. Finally, using the color transferring algorithm rearranged pixels comparison, color the grayscale images. Experiments on large numbers grayscale images show that this method is concise and clear, efficient for dyeing process and the results can be further used for automatic coloring of multiple targets color enhancement.
