Background Separation Encoding for Surveillance Purpose by using Stable Foreground Separation

An efficient encoding approach by separating background/foreground videos from a single video is proposed for surveillance applications. The required bit-rate becomes less than a half of that by a standard H.264 approach. The reduction comes from the employment of the low resolution background pictures with a low frame-rate. In addition, the foreground video is automatically handled so that the information amount becomes almost zero during the periods of no foreground objects. Therefore, storing videos or collecting multi-point surveillance videos at a surveillance center will save storage capacity or communications costs.
