Efficient Region-of-Interest Scalable Video Coding with Adaptive Bit-Rate Control

Table 6

FMO: four-layer coding versus six-layer coding (“STOCKHOLM”, 30 fps, 96 frames, GOP size 8).

Quantization parameters	Four layers; (640 × 360, and three HD layers) by using the FMO		Six layers; (three SD layers, and three HD layers)		Bit-rate savings (%)
