This contour phase correlation method is superior to the conventional phase correlation in two aspects. Firstly, the contours of images are extracted, and the phase correlation is applied to the contours of images instead of the whole original images, which is more efficient and robust. Secondly, when there are multiple peak values approximate to the maximum peak value in the δ function array, the corresponding translations can be regarded as candidate translations and calculated separately, and the best translation should be determined by the optimization of conformability of two images in the overlapping area.

本轮廓相位相关算法对常规的相位相关算法作了两点改进：(1)提取出图像的轮廓，只对二值化的轮廓图像进行相位相关计算，效率和鲁棒性提高；(2)当相位相关的δ函数阵列中存在多个和最大峰值比较接近的峰值时，将其对应的平移量都作为候选平移量，然后根据重叠区图像的一致性选取其中的最佳值。

实验表明：经 CCD Camera和图像卡采集的数字图像序列中存在着低频的图像抖动，即位相漂移。而且不同的 CCD Camera具有不同的漂移特点和程度，甚至在同一个图像行内的漂移也不完全一致。一般在图像行内相近的位置之间，位相漂移有明显的相关性，不同的图像行之间的漂移的程度相同，但没有相关性。最后本文还给出了一种位相漂移的修正方法
