| 摘 要： | 开发了一种图像增强技术,通过对图像进行网格化处理,对每个图像网格的亮度进行控制,调整误差扩展算法中的扩散因子.为了确保放电稳定性,对于给定的子场编码,选择能够产生稳定放电的子场排列方式进行显示.考虑到图像亮度分布特性,可以使用多个误差扩散因子选择阈值,设置多组不同的扩散因子,并应用于不同的图像网格区域,进一步增强低灰度级图像的显示能力.

| Abstract: | An image enhancement technology is developed.The brightness of each image grid is controlled by image processing grid,and the error diffusion algorithm expansion factor is adjusted.Then,selecting the sub-field arrangement that can produce a stable discharge to display for a given sub-field coding in order to ensure the stability of discharge.Taking into account the image brightness distribution characteristics,multiple error diffusion factors are used to select threshold in order to set different sets of sp... |
