摘要: This research mainly focuses in developing the algorithm for vision inspection inside TFT-LCD panels. The purpose of this is to extract defects precisely from source images with regular patterns and falloff illumination caused by vignetting effect. Specific spatial masks are generated Gaussian function means concept normal distribution. image decomposed into different frequencies scale-space representation. experimental result shows that defect can be effectively segmented smallest size less than 0.5pixel. optimized also provided paper shortening process time meet industrial needs AOI equipment. provides a novel complete solution scale manipulation processing.
