摘　　要：提出一种新的运动模糊图像盲恢复方法。通过计算模糊图像对数谱的拉东(Radon)变换,估计模糊方向;通过计算模糊图像的对数谱极小值,估计模糊尺度;同时,在MAP图像恢复方法的基础上,通过引入边缘能量控制先验约束,达到有效恢复图像,而后再进行去模糊、消除噪声的处理,保持图像的边缘信息。实验结果表明文章提出方法的有效性。A new method about blind restoration of motion blurred image is proposed. The motion direc- tion is estimated by the Radon transform of logarithmic spectrum, and the motion length is estimated by the minimum of logarithmic spectrum. Moreover, by adopting edge energy, a new image deblurring method based MAP is proposed to efficiently restore the image and preserve the information of edge on the basis of denoising. Experimental results demonstrate the effectiveness of the method.
