Overview of Scribbled-Based Colorization

Abstract

Hand-coloring is very useful when people draw pictures or produce movies, but it is also very time-consuming and expensive. Therefore, with the development of segmentation algorithms and deep learning, a lot of computer-assisted colorization algorithms have been invented, including user-guided colorization, semi-automatic colorization and automatic colorization. In this survey paper, we will only focus on scribble-based colorization in user-guided colorization and review the development on it. We will discuss various principles and methods among different kinds of scribble-based colorization algorithms. We will also compare visual result and performance of algorithms among colorization on grayscale image, colorization on sketch and colorization with networks to conclude their advantages and disadvantages.
