Colorization aims to adding colors to a grayscale image. This task is ill-posed in the sense
that assigning the colors to a grayscale image without any prior knowledge is ambiguous …

Colorization is a computer-aided process, which aims to give color to a gray image or video.
It can be used to enhance black-and-white images, including black-and-white photos, old …

RGB to gray conversion is an integral part of various computer vision applications such as
face detection, object detection and surveillance systems. The resource required for the real …

Editing a photo-realistic gradient mesh is a tough task. Even only editing the colors of an
existing gradient mesh can be exhaustive and time-consuming. To facilitate user-friendly …

There are a large number of grayscale or black-and-white images and video materials in
various film, television, picture archives, medical, and other fields. Coloring them can greatly …

In vector graphics, gradient meshes represent an image object by one or more regularly
connected grids. Every grid point has attributes as the position, colour and gradients of these …

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 …

Colorizing grayscale images so that the resulting image appears natural is a hard problem.
Previous colorization algorithms generally use just the luminance information and ignore the …

This paper proposes an information completion technique, GAN2C, by imposing dual
consistency constraints (2C) to a closed loop encoder-decoder architecture based on the …

The capability of inferring colours from the texture (grayscale contents) of an image is useful
in many application areas, when the imaging device/environment is limited. Traditional …
