point spread function estimation

基本解释

The research in-depth was made in image definition estimation, point spread function's parameter judgment and blurred image restoration techniques.
因此对于这类局部模糊图像复原技术的研究有相当大的实际意义和实用价值。
Point-spread function(PSF) plays a key role in image restoration. As a result, prior knowledge and posteriori estimation of PSF is usually used to restore image.
在图像恢复技术中，点扩展函数（PSF）是影响图像恢复结果的关键因素，所以常常利用先验知识和后验判断方法估计PSF函数来恢复图像。
The acquisition of the point spread function is the key point in non-blind restoration algorithms for image, it's very important to get the estimation of point spread function parameter.
在图像的非盲复原算法中，点扩展函数的获取是算法的关键，因而点扩展函数参数估计是图像复原中重要的一步。
