| 摘 要： | 该文分析了红外图像运动模糊产生的原理,建立运动模糊及复原数学模型.复原过程分包括构建点扩散函数和维纳滤波两部分.采用方向微分,双线性插值法求取模糊方向,通过微分自相关函数估算模糊尺度,从而构建最为近似的二维匀速直线运动的点扩散函数,并对运动模糊图像进行维纳滤波的复原.实验结果表明,针对有噪声的图像运动模糊复原,维纳滤波复原图像效果好,抗噪能力强.

| Abstract: | In this paper, the mechanism of a motion-blurred image generated from infrared imaging system was introduced. The mathematical model of direction differential, bilinear interpolation method and the related function to obtain the point spread function of two-dimensional uniform linear motion. It also explicates Wiener filter for motion-blurred infrared images, and compares their advantages and disadvantages. Finally, the algo- rithm is demonstrated through a series of experiments which reveal that the Wiener filter for restoration motion- blur imaging is more better than inverse filtering. |
