point spread function estimation

基本解釋

The research in-depth was made in image definition estimation, point spread function's parameter judgment and blurred image restoration techniques.
因此對于這類局部模糊圖像復原技術的研究有相當大的實際意義和實用價值。
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.
在圖像恢復技術中，點擴展函數(shù)（PSF）是影響圖像恢復結果的關鍵因素，所以常常利用先驗知識和后驗判斷方法估計PSF函數(shù)來恢復圖像。
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.
在圖像的非盲復原算法中，點擴展函數(shù)的獲取是算法的關鍵，因而點擴展函數(shù)參數(shù)估計是圖像復原中重要的一步。
