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...
In this paper, Robust Adaptive Image Coding (RAIC) is proposed to increase compression performance for Frame Memory Reduction in LCD Overdrive. The RAIC contains two techniques to improve the quality of decompressed images. The first is a Min-Max (of Block) Adaptive Uniform Quantization Coding (MMAUQC) to improve the quality of decompressed block images. The second is a Multiple Adaptive Quantization...
In this paper, Advanced Adaptive Image Coding (AAIC) is proposed to increase compression performance for frame delay memory applications. The AAIC contains two techniques to improve the quality of decompressed images. The first is a Mean Adaptive Image Coding (MAIC) to reduce the impact of noise on image compression. The second is a Content-based Bit Exchange Technique (CBBET) to provide an adaptive...
Blind separation of sources in convolutive mixtures involves the stability of an IIR filter for both direct and recursive structures. In this communication, in the case of two convolutive mixtures of two sources, we are interested in sufficient conditions on mixture filters which imply the stability of this IIR filter. Various stability criteria of IIR filters are studied in order to obtain a simple...
Blind separation of sources is now a well known problem, and various methods have been proposed for instantaneous mixtures, and convolutive mixtures of narrow-band sources. In this paper, we present adaptive algorithms for separation of wide-band signals, for convolutive mixtures modeled by Finite Impulse Response (FIR) filters. The algorithms estimate coefficients of FIR filters using independence...
