image filter的用法和樣例：
例句
- Thus, it is imperative that image filter kernels be optimized for execution in the lowest possible number of processor cycles.
于是，重要的是，圖像濾波器內核必須被優(yōu)化，從而在盡可能少的處理器周期內完成。 - Since a video stream is really an image sequence moving at a specified rate, image filters need to operate fast enough to keep up with the succession of input images.
既然一個(gè)視頻流事實(shí)上是一路以特定速率移動(dòng)的圖像序列，圖像濾波器需要以足夠快的速度運行，以跟上圖像連續不斷的輸入。
