Image colorization using anisotropic diffusion

Abstract EN

Adding colors to all pixels in monochrome image are difficulty performed.

It requires considerable user intervention and remains a tedious, time-consuming, expensive task with no certain results.

The previous methods have not the wanted color-scale and the harmony in colors used.

This paper presents semi-automatic image colorization, where the user only needs to annotate the image with a few desirable color scribbles depending on the user’s choice and the indicated colors are automatically diffused to produce a fully colorized image.

The execution depending on the geometry and structure of the monochrome luminance input, given by its gradient information, The color is then diffused by solving a partial differential equation (Anisotropic Diffusion Equation) that annotate a few color scribbles provided by the user, with firmness in the original gradient information in image.

The approach suggests an semi- automatic method that minimizes the amount of human work and the results are of high efficiency from the previous methods.
