WebFeb 4, 2011 · The sift function only works in greyscale, so the input should be 1 channel as well. If the input has 3 or 4 channels instead of 1 (such as RGB, or RGB with alpha) , sift will convert the input image into greyscale before running its algorithm. You can convert to greyscale yourself before using sift with WebMar 13, 2024 · 3.求出样本图像的特征点坐标和测试图像的特征点坐标，找出这两坐标矩阵的H变换公式（利用RANSAC算法），将H变换公式对right图像做透视变换，得到拼接后的右边图像 4.将left原图赋给result对应的ROI区域，大功告成。
