RSS订阅原创 No Free Lunch 定理
我们不可能找到一个prediction model对所有数据都work。在训练集特别work的，在其他集肯定特别不work，所以平均起来，所有model的prediction rate都是一样。“[...] all algorithms that search for an extremum of a cost function perform exactly the same, when ave

原创 多核跟踪
Multiple kernels have several advantages over single kernel. For, example, multiple kernels can alleviate the singularity and improve the kernels observability to the motions. Multiple kernels are

原创 OpenCV Tips
IplImage *img_8U = cvCreateImage(cvSize(img->width,img->height),IPL_DEPTH_8U,1);cvCvtColor(img, img_8U, CV_RGB2GRAY); //原图像转换成灰度图 IplImage *img_32F = cvCreateImage(cvSize(img->width,img->hei

转载 OpenCV中创建Iplimage的方法
1，如果是从新创造一个Iplimage，则用IplImage* cvCreateImage( CvSize size, int depth, int channels )，它创建头并分配数据。注：当不再使用这个新图像时，要调用void cvReleaseImage( IplImage** image )将它的头和图像数据释放！2，如果有图像数据没有为图像头分配存储空间（即，没有为IplI

原创 Learning-based visual tracking
Underlying learning-based tracking algorithms lies a data-driven procedure. In most cases, a binary classifier (except [13]) that discriminates the object of interest and the background is learned,

原创 Visual Tracking 和 Motion Estimation的区别
It should be emphasized that visual tracking is different from motion estimation. The latter concerns only two successive frames; while the former concerns the motion estimation of a whole video se
