摘　　要：传统渐变技术在融合彩色图像过程中,经常出现质量不稳定的现象,渐变后的图像不够自然。为了提高渐变后图像质量,基于灰度融合理论设计了一种新的彩色图像渐变技术,该技术主要分为两个阶段,第一个阶段为彩色图像灰度处理,主要通过调节目标与背景对比度来改变图片性质;第二个阶段为彩色图像渐变,利用彩色图像采样、彩色灰度图像交叉融合和融合后图像渐变三步来完成,并引进一种新的非线性插值算法改善图片质量。为检测该设计的实际应用效果,与传统渐变技术进行了对比实验,结果表明,新的渐变技术得到的渐变序列更加平滑,渐变过程十分稳定,渐变后的图像效果自然,所需成本更低,渐变效果适应性强。In the process of color image fusion, traditional gradient technology often appears unstable quality, and the image after gradual change is not natural enough. In order to improve the quality of gradual change image, a new color image morphing technology is designed based on gray fusion theory. The technology is mainly divided into two stages. The first stage is color image gray processing, mainly by adjusting the contrast between the target and the background to change the character of the picture. The second stage is the color image gradual change, which is completed by the color image sampling, the color gray image cross fusion and the fusion of three steps after the fusion, and introduces a new nonlinear interpolation algorithm to improve the image picture quality. In order to test the actual effect of the design, the comparison experiment with the traditional gradient technology show-s that the new gradient technology is more smooth, the gradual process is very stable, the image after the gradual change is natural, the cost is lower, and the gradient effect is adaptable.
