Pseudo-Coloring with Histogram Interpolation

In this paper, a pixel based pseudo coloring is presented. The proposed approach consists of two parts: luminance matching and pixel coloring. Given a monochrome input image and a color reference image, luminance matching between the two images is performed. If there is no matching between, a interpolation scheme is used to interpolate the chromatic histograms of reference image. By this doing, it ensures each pixel in the input image has its corresponding chromatic information in the reference image. By the luminance and chromatic information, a colored input image is obtained. Two examples are provided to justify the proposed pseudo coloring approach. The simulation results indicate that the proposed approach is feasible.
