Abstract :
This paper presents an improved block truncation coding (BTC) for color image compression in LCD overdrive. To improve the BTC, single bit plane is used to represent the R, G and B bit planes and correct the two representative levels. Simulation results show that the proposed algorithm can significantly improve the compression ratio of the BTC from 4:1 to 6:1 with the limited performance losing about 0.297 dB. Compared with other competitive improved BTC such as VQ-BTC, the proposed algorithm also performs 2.107 dB better.
