The Design of Electronic Paper Image Filtering Based on Gabor Filters

  • 摘要: 采集电泳电子纸(EPD)的边缘纹理、鬼影图像时,需避免外界光照条件的干扰,包括光源方向、明暗和色彩等.针对EPD显示画面采集过程中受到的光干扰问题,设计了一种基于Gabor滤波器的图像滤波系统.对于受光干扰的单一灰阶图像,先通过Gabor滤波器降低光照变化和噪声对图像的影响,再通过闭运算进行边缘补偿;对于受光干扰的彩色图像,先提取图像的RGB分量,分别对各分量进行Gabor滤波,最后将3组分量重新组合成彩色图像.结果表明:该系统在单一灰阶图像、彩色图像中对光干扰的消除率分别达到39.9%和39.7%.研究结果对降低采集EPD图像时的光干扰具有重要意义.
