基于图像对的三维重建，利用sift和区域增长算法的稠密匹配以达到三维重建的目的-Sift and regional growth algorithm based on three-dimensional reconstruction of the image on dense matching in order to achieve the purpose of the three-dimensional reconstruction

种子增长算法，根据种子点位置以及设定的阈值，进行快速区域增长-Seed growth algorithm, according to the seed point location and the set threshold, the rapid regional growth

区域增长算法核心，可以根据图像所在区域 找到同一区域的像素(Kernel of region growth algorithm)
