cvtColor(m_img,img_grey,CV_BGR2GRAY);
img_gpu.upload(img_grey);
//cout<<"upload img to gpu finished..."<<endl;
SURF_GPU gpusurf(2000);
gpusurf(img_gpu,GpuMat(),img_keypoint_gpu,img_descriptor_gpu);
//cout<<"compute keypoints and descriptors finished...."<<endl;
gpusurf.downloadKeypoints(img_keypoint_gpu,img_keypoints);
//cout<<"download keypoints_gpu to keypoints finished..."<<endl;
//cout<<"Constructor end!"<<endl;
有这么一段GPU代码,对gpu不是很了解。。。。如果要改成普通的surf,要怎么改?能给点建议吗(用什么函数。。。。)
谢谢大家了
