Abstract
In object-based coding, bit allocation is performed at the object level and temporal rates of different objects may vary. The proposed algorithm deals with these two issues when coding multiple video objects (MVOs). The proposed algorithm is able to successfully achieve the target bit rate, effectively code arbitrarily shaped MVOs with different temporal rates, and maintain a stable buffer level
