基于HVS模型及边缘检测的点扩散算法

摘要

According to the artifical texture made by conventional dot diffusion in the image processing and the deficiency of edge outline details processing in image,a dot diffusion halftoning based on HVS model and Edge Detection is proposed,which takes the idea of iteration method and visual features of human eyes.the algorithm can decrease the artifical texture of output images,preserve the detail information of image outline and obtain the images with better quality.%针对传统点扩散算法在处理图像时会产生人工纹理且对于图像的边缘轮廓细节处理不够完善的缺陷,提出了一种基于HVS模型及边缘检测的点扩散算法,借鉴迭代法的思想,考虑人眼的视觉特点,减少输出图像的人工纹理,保留图像轮廓细节信息,获得了更好的图像质量。
