摘　　要：针对目标和背景在同一平面的图像,提出一种双阈值分割方法获取图像由目标过渡到背景的边缘区域,并将提取的边缘区域平均梯度用于图像清晰度的评价,评价效果较好.Aiming at the image in which target and background are on the same plane, we offered a new image segmentation method acquiring image edge by two thresholds. Experiments show that we can evaluate image sharpness by the average grads of the image edge acquired by this method and the result is effective.
