Hello,
I have to detect keypoints on big sized images (about 6mb). I have tried SURF and it works fine and now I'm trying to use SIFT. The code is simple:
cv::Mat image = imread("../images/IMG_3849.jpg", CV_LOAD_IMAGE_GRAYSCALE);
cv::SiftFeatureDetector detector;
std::vector<cv::KeyPoint> keypoints;
detector.detect(image, keypoints);
cv::SiftDescriptorExtractor extractor;
cv::Mat descriptors_object;
extractor.compute( image, keypoints, descriptors_object );
However when I run this code, I get the error "OpenCV Error: Insufficient memory - Failed to allocate 286654468 bytes".
Anyone knows why this might be happening?
Thank you!
