point-spread function psf

基本解釋

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(shù)中，點(diǎn)擴(kuò)展函數(shù)（PSF）是影響圖像恢複結(jié)果的關(guān)鍵因素，所以常常利用先騐知識(shí)和後騐判斷方法估計(jì)PSF函數(shù)來(lái)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(shù)實(shí)際求解比較睏難，一般信道均衡使用傳統(tǒng)均衡技術(shù)，因而必須首先知道點(diǎn)擴(kuò)展函數(shù)，但實(shí)際條件下點(diǎn)擴(kuò)展函數(shù)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(wèi)了恢複圖像和確定點(diǎn)擴(kuò)散函數(shù)需要適儅的先騐知識(shí)。
