| 摘 要： | 针对储粮害虫图像复原中点扩展函数矩阵逆矩阵不存在的情况，提出了一种用奇异值分解和Moor-Penrose广义逆来实现图像复原的方法，通过将矩阵做奇异值分解再求其Moor-Penrose广义逆，最后得到原始图像的一个很好的近似值，并在Matlab7．0上实现了算法。结果表明该方法在复原由运动造成的图像模糊方面有很好的效果。

| Abstract: | In allusion to no inverse matrix of point spread function matrix in the image restoration of stored-grain pests,a kind of method of realizing the image restoration by using singular value decomposition and Moor-Penrose generalized inverse was proposed.Through the singular value decomposition of the matrix, Moor-Penrose generalized inverse was calculated.Finally,a good approximation of the original image was obtained and the algorithm was realized on Matlab.The results showed that the method had a good effec... |
