土粒流运动图像模糊退化的恢复

摘要

It describes the motion-blurred images of back-throwing latent soil under up-cut rotary cultivation. Mathematics models of the process are set up and several methods of restoration of the motion-blurred images are discussed. According to the characteristics and causes of the motion-blurred images of back-throw soil, different restoration methods are adopted. In this paper, wienerfilter with optimal windows is used to set different areas of the images and to determine point spread function of each image. A quite satisfactory result is achieved. The study will reduce the difficulty and improve accuracy in the late image processing.%分析了潜土逆转旋耕被抛土粒流运动图像模糊退化机理，依据土粒流运动图像的特点，针对不同的退化机理分别采用了不同的恢复方法. 该文采用带最优窗的维纳滤波恢复方法，对土粒流运动模糊退化图像适当进行分区，确定了合适于各自图像区域的点扩展函数，获得了较为满意的恢复效果，为降低后续处理的难度和提高处理精度提供了可靠保证.
