We present an effective image colorization method in which the user only needs to scribble in key areas of a monochrome image with intended colors. Computation complexity is reduced by introducing a simple weight function. Using sub-sampling and interpolation, the colorization process is accelerated without sacrificing the image quality. Cross-object color infiltration is prevented by using edge information...
This paper presents a new method for image colorization based on manually added scribbles. We determine color propagation paths in the image by minimizing the geodesic distance from the scribbles using Dijkstra algorithm. After that, chrominance blending is performed to colorize the image. Our contribution lies in proposing the competitive approach for selecting an appropriate type of the path cost...
Dithering has been established as an important technique for producing visually appealing images on many printing and display devices. Although various error diffusion filters have been developed for dithering, there has been in general a lack of results guided by both visual quality and objective measure on the image quality. In this paper we present a dithering method by designing the error diffusion...
In this paper, a hybrid method is proposed to colorize grayscale images. First, the input image is colorized by the fast colorization method, which is based on the technique of color blending obtained effectively from a weighted distance function computed from the luminance channel. Second, the neighborhood filter approach, which restores a pixel by taking a weighted average of the values of neighboring...
In order to convert a color image into a monochrome one, luminance components of the color image are extracted, and are used in the typical photo re-touching software. This luminance extraction is useful and enough for obtaining a monochrome image in most cases. However, saliencies of the image included only in the chrominance components are not preserved at all. In this paper, we propose a new color...
