问题描述

有人知道OpenCV 2.2的SIFT实现示例的链接.问候,

Does someone know the link of example of SIFT implementation with OpenCV 2.2.regards,

推荐答案

下面是一个最小的示例:

Below is a minimal example:

#include <opencv/cv.h>
#include <opencv/highgui.h>

int main(int argc, const char* argv[])
{
    const cv::Mat input = cv::imread("input.jpg", 0); //Load as grayscale

    cv::SiftFeatureDetector detector;
    std::vector<cv::KeyPoint> keypoints;
    detector.detect(input, keypoints);

    // Add results to image and save.
    cv::Mat output;
    cv::drawKeypoints(input, keypoints, output);
    cv::imwrite("sift_result.jpg", output);

    return 0;
}

在OpenCV 2.3上测试

Tested on OpenCV 2.3
