摘要

近年来，线投影法是一种比较流行且简便的彩色到灰度转换方法。提出了一种新的基于边缘检测的线投影全局映射方法。首先，计算各候选灰度图像边界点个数与彩色图像边界点个数之比;所有的灰度图像都是通过穷举搜索法确定的。其次，选取最大比值作为最优直线投影方向;本文提出的方法主要关注图像的边缘信息。实验结果表明，对于具有明显区域特征的图像，该方法优于其他典型方法。

A New Color-to-Gray Conversion Method Based on Edge Detection

In recent years, the line projection approach is popular and simple for the color-to-gray conversion. This paper presents a new line projection global mapping method based on edge detection. Firstly, we calculate the ratio of the number of each candidate gray image boundary points to the number of the color image’s. All the gray images are determined by exhaustive search method. Secondly, we choose the maximum ratio as the optimal line projection direction. The method proposed in this paper focuses on the edge information of the image. Experimental results show that the proposed method is superior to the typical other methods in terms of the images with obvious regional features.
