|Abstract:||The main features of our proposed wavelet-based video coder include: 1) a user-specified region of interest selection as to which the region can be changed by the user at any I-frame; 2) a dynamic region tracking technique by which the video is tracked and updated according to motion activity and 3) an adaptive bit allocation that allows the user to specify the relative quality between the foreground and the background. This architecture guarantees a high video quality in the region of interest while reducing the overall bit rate and the computation time. Experimental results confirm that the approach produces a good video quality even under low bit rates.|
