一种改进的基于过度分割的图像彩色化方法
An Improved Colorization Algorithm for Gray-Scale Image Based on Over-Segmentation
-
摘要: 黑白图像的彩色化是图像处理领域一个活跃的、有挑战性的研究课题。该文在总结图像彩色化方法的基础上，重点分析了Levin方法；针对这种方法处理大尺寸图像速度较慢的问题，提出先对图像进行过度分割，再以区域为基本单元进行彩色化的方案。实验表明，该方法能够在几乎不影响彩色化效果的前提下，显著提高处理大尺寸图像的速度。

Abstract: Colorization of gray-scale image is in general an active and challenging area of research in image processing. In this paper current colorizing algorithms are summarized, of which Levins method is analyzed in particular. According to the speed dropping of Levins method in processing large scale images, a new scheme based on over-segmentation is proposed. Experiments show that the new scheme can remarkably quicken the processing of large scale images, nearly without degrading the colorizing effect. -
