VC6.0平台下匀速模糊图像的模糊距离估计与复原

Fuzzy distance estimation and restoration of uniform motion-blurred image based on VC6.0

由于图像在采集过程中,物体与采集设备的相对运动会造成图像的运动模糊.在图像模糊的点扩散函数未知的前提下,对水平匀速直线运动造成的模糊图像进行频谱分析,得到点扩散函数、模糊距离、频谱条纹个数的关系,准确的估计出了模糊距离和点扩散函数,利用逆滤波方法恢复出原图像.

On the process of image acquisition,relative motion between object and acquisition equipment causes blur.On the premise of that the point spread function of motion-blurred image is unknown,analyses the spectrum of blurred image from horizontal uniform linear motion and obtains the relation among the point spread function,the blurred distance and the number of spectrum fringe,through which,the fuzzy distance and point spread function are estimated accurately and the original imagine is restored by using inverse filtering method.
