Abstract :
The authors present a new method for optimum rate allocation which does not require any assumption about either the integrality of the allocated bit rate, or on the convexity of the distortion curves. Numerical results are presented for the DCT coding of still images showing a noticeable improvement in the performance with no increase in the complexity
