Rewritten Blob tracking tests Project

Although the Blob tracking tests project officially provided by opencv has many algorithm features that can be verified by one compilation, beginners often do not know what commands to write to use this project, to help me understand this vs framework, I wrote a very simple Blob tracking tests project that can be used directly. The biggest function of this project is simple to use, simple code, and easier to read than the code of the original project. However, the function is much less, which may cause memory leakage, however, it can help beginners get started quickly with the vs framework. Press f5. In use, you only need to replace the main function and runblobtrackingauto function with the following function.

Static int myrunblobtrackingauto (cvcapture * pcap, cvblobtrackerauto * ptracker, char * fgaviname = NULL, char * btaviname = NULL) {int nframenum = 0; iplimage * pimg = NULL; iplimage * pmask = NULL; iplimage * PFG = NULL; int key = 0; For (nframenum = 0; pcap & (Key = cvwaitkey (2 )! = 27); nframenum ++) {pimg = cvqueryframe (pcap); If (! Pimg) break; cvshowimage ("frame", pimg); ptracker-> process (pimg, pmask); PFG = ptracker-> getfgmask (); cvshowimage ("PFG ", pfG); cvshowimage ("Mask", pmask); // cvreleaseimage (& pimg); // cvreleaseimage (& pmask);} return 0;} int main (INT argc, char * argv) {cvcapture * capture = NULL; cvblobtrackerautoparam1 Param = {0}; cvblobtrackerauto * ptracker = NULL; // framework class defmodule_fgdetector * pfgmodule = NULL; // This is defined in the first file.

The effect is as follows: The image is collected from the camera on the left and the foreground mask on the right. :
