In computer vision, sometimes we need to extract training data from videos. So a nice video annotation tool is of great importance. I developed this tool couples of years ago. I wish this video could help you learn much faster about how to use this tool in your project. If you find any problem with the software, please fell free to leave comment here or send me email.
You can download the tool at http://www.phyxs.com/down_load/videoa...

PS: I had published a video contains the content of this video, but that one is too long and hard to find connection to the tool I published.
