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(fù)原技術(shù)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(fù)技術(shù)中，點擴展函數(shù)（PSF）是影響圖像恢復(fù)結(jié)果的關(guān)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(fù)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(fù)原算法中，點擴展函數(shù)的獲取是算法的關(guān)鍵，因而點擴展函數(shù)參數(shù)估計是圖像復(fù)原中重要的一步。
