An Intelligent Display Scheme of Soccer Video on Mobile Devices

The rapid progress of the multimedia signal processing has contributed to the extensive use of multimedia devices with small liquid crystal display (LCD) panel. With the proliferation of mobile devices with a small display, the video sequences captured for normal viewing on standard TV or HDTV may give the small-display viewers uncomfortable experience in understanding what is happening in a scene. For instance, in a soccer video sequence taken by a long-shot camera technique, the tiny objects (e.g., soccer ball and players) may not be clearly visible on the small LCD panel. Thus, an intelligent display technique is needed for small-display viewers. To this end, one of the key technologies is to determine region of interest (ROI), whenever ROI display is considered more effective.
