基于调色板分析及误差扩散抖动的迷彩仿造

仿造迷彩是针对特定的环境背景生成的伪装迷彩。在迷彩纹理设计上,无规则的、点阵式的数码迷彩相对传统迷彩具有更好的迷惑效果。提出一种新的仿造数码迷彩方法,在调色板颜色分类排序及直方图合理分析的基础上提取四种主色,结合抖动半色调方法统计四主色比例,并运用随机像素点集的方式生成迷彩图案。实验证明,该方法生成的迷彩图与参照背景图能自然融合,达到较高的伪装隐蔽效果。

Design of imitated camouflage based on palette analysis and error diffusion dither

Imitated camouflage is the camouflage pattern designed based on special environmental background. With ruleless pattern and dot matrix characteristics, the concealment of digital camouflage is better than the traditional one. A new imitated camouflage method is presented in the paper. Four main colors are selected based on palette sorting and histogram analysis, the color proportion is calculated with dither halftone, and the camouflage pattern is generated by applying the random pixel array at last. Experimental results indicate that, the camouflage images can blend with the background figures naturally and show good camouflage effects.
