| 摘 要： | 由于图像恢复的最终目的是要获得清晰的图像,便于提取有用信息,而点扩展函数的设置是影响运动模糊图像恢复质量的关键问题.若在未知模糊方向的情况下,对图像进行预恢复,并对预恢复结果进行清晰度评价,当模糊方向在取值范围内遍历,总能获得一幅相对清晰度最高的图像,该图像对应的模糊角度即为鉴别出的模糊方向,同时恢复出了模糊图像.实验表明,该算法可以准确地识别图像运动模糊方向,绝对误差不超过3°.

| Abstract: | Setting the point spread function of motion blurred image is the key problem in the image restoration.For the motive of restoration is to get a clear image convenient for extraction useful information.If the blurring direction is unknown,we can pre-restore the blurred image and measure the definition of the pre-restoration result,while the direction angle is traversed in a given filed,a clearest image is obtained;thus the degree of the angle corresponding to the clearest image is the identified direction.Co... |
