A discrete orthogonal polynomial method is put forward for curve fitting sub - pixel edge detection algorithm , which decomposes two - dimensional curve fitting into one - dimensional curve fitting , and improves the reliability and computation speed of the algorithms
引入離散正交多項(xiàng)式，提出了一種新的曲面擬合亞像素邊緣檢測(cè)算法。該算法將二維曲面擬合分解為一維曲線(xiàn)擬合，大大提高了算法的可靠性和速度。
In order to detect the edge contours of the object in images , several edge detectors are firstly introduced and we make a comparison of them in performance . a method for fitting a two - dimensional curve based on slopes of the curve is also shown
從圖像序列中檢測(cè)運(yùn)動(dòng)目標(biāo)并估計(jì)其三維運(yùn)動(dòng)和結(jié)構(gòu)，首先要從圖像邊緣提取開(kāi)始，本文先對(duì)幾種常用邊緣檢測(cè)算子性能進(jìn)行綜合比較，接著闡述了一種基于邊界斜率的二維曲線(xiàn)形狀描述方法。
