Abstract
A correlation-inheriting vector quantisation (VQ) image coding algorithm is presented to re-encode the output indices of VQ after analysing the correlation inheritance of the indices' neighbourhood. Simulation results indicate that this algorithm can compact the VQ index to achieve an ∼21:1 compression ratio on average. In accordance with this new algorithm, an efficient very large scale integration architecture is also derived that, after synthesis, achieves a system clock rate of 110 MHz using a 0.35 µm complementary metal-oxide-semiconductor standard library.
