彩色图像配准的matlab程序

以下是一个基本的彩色图像配准 MATLAB 程序：

% 导入两张待配准的彩色图像
image1 = imread('image1.jpg');
image2 = imread('image2.jpg');

% 转换为灰度图像
gray1 = rgb2gray(image1);
gray2 = rgb2gray(image2);

% 检测图像特征点
points1 = detectSURFFeatures(gray1);
points2 = detectSURFFeatures(gray2);

% 提取图像特征描述符
[f1, vpts1] = extractFeatures(gray1, points1);
[f2, vpts2] = extractFeatures(gray2, points2);

% 通过匹配图像特征点进行配准
indexPairs = matchFeatures(f1, f2);
matchedPoints1 = vpts1(indexPairs(:, 1));
matchedPoints2 = vpts2(indexPairs(:, 2));

% 估计仿射变换矩阵
tform = estimateGeometricTransform2D(matchedPoints1, matchedPoints2, 'affine');

% 应用仿射变换
Rfixed = imref2d(size(image1));
registered = imwarp(image2, tform, 'OutputView', Rfixed);

% 可视化配准结果
figure;
imshowpair(image1, registered, 'montage');
