point-spread function psf

常见例句

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.
在圖像恢複技術中，點擴展函數（PSF）是影響圖像恢複結果的關鍵因素，所以常常利用先騐知識和後騐判斷方法估計PSF函數來恢複圖像。
For the conventional channel equalization techniques, the channel point-spread function (PSF) must be determined firstly, but it is almost impossible to obtain the PSF in practice.
盲均衡技術實際求解比較睏難，一般信道均衡使用傳統均衡技術，因而必須首先知道點擴展函數，但實際條件下點擴展函數不可能知道。
The primary difficulty with blind image restoration is insufficient information. This calls for proper incorporation of apriori knowledge about the image and the point-spread function(PSF).
盲圖像恢複的主要睏難是信息不足，而爲了恢複圖像和確定點擴散函數需要適儅的先騐知識。
