An efficient distortion measure based on a novel subspace is proposed for 4 × 4 image mean residual vector quantisers (MRVQ). The dimensionality of the coder distortion measure is reduced from 16 to 4, maintaining the visual image quality. The computation complexity and memory requirements of the quantiser are significantly reduced.
