| 摘 要： | 1 投影迭代公式在线性空不变条件下的简化图像复原的算法很多,本文采用Huang提出的投影迭代复原算法,它适用于线性模糊图像的复原.对线性成像系统,模糊图像g(x, y)与对应的原始图像f(x,y)的离散数字化关系为g=Df,其中g,f分别是g(x,y),f(x,y)的向量表示,D是由系统点扩展函数决定的转换矩阵,则复原迭代公式为

| Abstract: | The restoration of uniform motion blurred images is studied by means of the projection iterative method. The projection iterative fornmla is simpli- fied for linear shift-invariant blurred images.A method is proposed to esti- mate the point spread function called as the power spectrum distinguished method. A scale formula is proposed as well in this paper to reduce informa- tion loss, if the negative values appear during the image processing. A practical deeply blurred image was restored efficiently. |
