matlab 2011b中的函数cvexShowMatches()显示匹配图像是非常不爽。
执行如下代码:
I1 = imread('cameraman.tif');
I2 = imresize(imrotate(I1,-20), 1.2); points1 = detectSURFFeatures(I1,'MetricThreshold',10000); points2 = detectSURFFeatures(I2,'MetricThreshold',10000); [f1, vpts1] = extractFeatures(I1, points1); [f2, vpts2] = extractFeatures(I2, points2); index_pairs = matchFeatures(f1, f2) ; matched_pts1 = vpts1(index_pairs(:, 1)); matched_pts2 = vpts2(index_pairs(:, 2)); % Note that there are still several outliers present in the data, but
% otherwise you can clearly see the effects of rotation and scaling on % the display of matched features. cvexShowMatches(I1,I2,matched_pts1,matched_pts2); % show matching points 显示的图像如下:
这非常不方便,看起来一点都不清楚。
于是自己修改了cvexShowMatches() 这个函数,这样,就可以显示下面的图像了。是不是比较方便了?
修改好的函数在最后。请下载。
