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算法。該算法將二維曲面擬合分解為一維曲線擬合,大大提高了算法的可靠性和速度。
( 3 ) compare the complexity and precision of the polynomial method and orthogonal polynomials method used in geometrical adjustment , an experiment is made ; some surface fitting method used in spatial co - registration of multiresolution image are studied and experiments are made to show their different in effects ; in order to increase the spectral inherit , we make a histogram match in images to be fused 比較了圖像幾何校正的多項(xiàng)式方法和正交多項(xiàng)式方法在復(fù)雜度與精度上的差異,進(jìn)行了仿真實(shí)驗(yàn);研究了不同插值技術(shù)在圖像配準(zhǔn)中的應(yīng)用,對(duì)不同插值方法的效果進(jìn)行了比較,給出了示意圖;為消除圖像灰度級(jí)不匹配對(duì)融合結(jié)果的影響,對(duì)待融合圖像的灰度直方圖進(jìn)行了匹配處理。
