Video and Image Processing Blockset 2.8

Multimedia I/O, Video Viewer, and Display Blocks

The Video and Image Processing Blockset can import multimedia files, such as AVI, MPEG, WMA, or any file type supported by Windows Media (Windows platform only). Video viewer and display blocks enable you to view the status of the video stream in real time throughout the model. You can start, stop, pause, and step through simulations one frame at a time. These time-saving features enable rapid design and debugging of your video and imaging system models.

The Video and Image Processing Blockset lets you:

• Send live video data to a video output device, monitor, or camera connected to the system
• View the video signal on your PC or workstation screen
• Write the input to an array in the MATLAB workspace
• Display RGB or intensity video streams or images
• Write video frames to a multimedia file to analyze and share results
• Use the MPlay GUI to easily view video signals in Simulink models and to view video from files or the MATLAB workspace

The blockset enables you to insert text and graphic objects into the video stream, overlay and mark regions, or annotate and combine images.

A people-tracking application uses Blob Analysis block and Kalman filtering susbsystem to detect and track each person in the video frame. Further processing ensures that the same people are tracked from one frame to the next, and a bounding box highlights each individual. Click on image to see enlarged view.
