Abstract:
A method for allocating bits to encode each frame of an image sequence, each of said frame having at least one object, said method comprising the steps of:(a) determining a target frame bit rate for the frame; and(b) allocating said target frame bit rate among the at least one object, wherein said allocating step comprises the step of allocating said target frame bit rate in accordance with a target object bit rate for the at least one object, wherein said target object bit rate for the at least one object is selected in accordance with a mean absolute differences (Mad) of said object in accordance with: ##EQU6## where Mad.sub.i is the mean absolute difference (Mad) of an object i, n is a number of said objects in the frame, T.sub.frame is said target frame bit rate and V.sub.i is said target object bit rate for object i.
