摘要
对光照度不均的原图进行先膨胀后腐蚀处理,通过顶帽变换去除提取到的图像背景,再对原图进行边缘检测,提取边缘信息来弥补由于顶帽变换造成的边缘信息缺失,可以有效地去除阴影,保持连续的边缘。
The original images with uneven illumination are dealt with open operation first and then the image background are extracted with top-hat transform.The edge information of the original image is detected and extracted to compensate the edge deficiency generated from top-hat transform.
