2015-12-10 07:27:15 -0600 | asked a question | how can merge the video data to a matrix? Hi, I am working with a video sender. That can communicate with it by the SDK(Software Development Kit). Every time a frame is ready then run an internal event below (the name is video-available) ,that we can do our processing in this event. we know frame will be send with ENCODE-VIDEO_EVENT* pointer.and the data structure is: typedef struct { char* buff; int size; } how can merge the video data to matrix? Many Thanks. |

2015-09-23 13:09:19 -0600 | asked a question | cars fading in traffic jam Hi, i want to calculate traffic jam. To do this I got the contours of the foreground.. But I have a big problem. If the traffic for a long time.And the cars do not move for several minutes. As a result, the cars will be part of the background(the cars fade). How can I solve this problem. Many Thanks. |
