| 摘 要： | 多灰度图像的激光雕刻算法是研究如何通过激光雕刻来逼真再现具有连续色调的灰度图像。作者构造了“多级误差扩散”的算法,利用图像四叉树来表示输入灰度图像与输出图像之间的区别,并在全图的范围内按照“最大亮度”规则选择误差扩散的像素,这样有效的消除了模式噪声、边界效应与黑洞效应,使利用激光雕刻出的图像很好的再现了原始图像,具有良好的视觉效果。

| Abstract: | The laser marking algorithm of Multi-Grey image mostly research how to reappearance continuous tone image through laser marking.The author constitutes the algorithm of Multi-Scale error diffusion and utilizes the quadtree of image to express the difference between the input Grey-Scale images and the output images.Then the author searches the brightest region of a given image via the "maximum intensity guidance" for assigning dots and diffuses the quantization error.It can eliminate pattern noise and boundary effects and black-hole effects and make output image of laser marking finally well reappearance. |
