N2 - The large quantity of data associated with visual information necessitates the use of compression techniques. In this paper, we propose a novel approach (compressed domain technique) to implement spatial scalability directly on the compressed image/video data. In contrast to the spatial domain technique (baseline for comparison), the proposed technique removes the unnecessary decompression and re-compression procedures. The computational complexity is greatly reduced by using certain approximations. We note that depending on the image/video content, only marginal quality degradation (almost unnoticeable subjectively) may be introduced. Simulation results confirm the substantial reductions in computational complexity of the proposed technique at a comparable performance to the spatial domain technique.
