Abstract :
In this paper, DWT-Based Multi-Adaptive Image Coding (DBMAIC) is proposed to increase compression performance for Frame Memory Reduction in LCD Overdrive. The DBMAIC development is based on DWT-Based Adaptive Mode Selection (DAMS)[9] integrated with Adaptive-Threshold Technique (ATT). ATT is proposed to reduce blocking effect and increase adaptability of DAMS. Experimental results show that the performance of the proposed method is much better than DAMS and that of conventional schemes.
