ABSTRACT Gray image coloring is utilized to increase the visual appeal of images such as old black and white photos, movies or scientific illustrations. Most of authors working in coloring of gray scale images have used primitive methods for coloring which are both inaccurate and limited. In this paper we propose a new technique for computer coloring gray scale images. This technique works for texture based images like natural scenes. It's based on segmenting the image into different regions according to their textures. Real colors of the image can then be obtained by classifying these textures to predefined texture classes. Recognition of these textures is performed by matching these textures with a training set stored in a special database. We validate the efficiency of our coloring system by coloring several sets of natural gray images with high quality real colors.

    ABSTRACT: Since the human visual system is sensitive to colors rather than gray shades, we aim to emphasize the appearance of black and white movies and recolor them to obtain near natural colored movies that look like their original colors. The goal of our research is to implement a powerful automatic coloring system that is suitable for coloring movies with high quality colors and in fast time as possible. Our proposed system based on colorizing the movie shot by shot rather than frame by frame, so that different techniques are presented like shot cut detection, motion estimation, similarity features between images and colorization. By this paper we have succeeded to propose and implement a complete automatic colorization system specified for movies and we nearly achieve our goals.

    ABSTRACT: Image colorization is a new image processing topic which refers to recolor gray images to look like the original color images as possible. Different methods appeared in the literature to solve this problem, the way which leads to thinking about decolorization which means eliminating the colors of color images to just small color keys, aid in the colorization process. Due to this idea, decolorization is considered as a color image encoding mechanism. In this paper we propose a new decolorization system depends on extracting the color seeds using morphology operations. Different decolorization methods was studied and compared to our system results using different quality metrics.
