Abstract :
One of the important factors for image coding of vector quantization (VQ) is the response time of encoding. A new inequality is derived for efficient codeword search of vector quantization. This new inequality is applied to VQ image coding. Experimental results confirm the derivation of the new inequality compared with the method of using the previous vector candidate and triangular inequality elimination (TIE) proposed by Huang and Chen (1990)
