Abstract

in the field of multimedia technology, image compression technology is at the core position, which directly affect the quality of the large-scale broadcasting and television project. In the traditional wavelet multimedia video image compression technology, the shortcomings of wavelet coefficient characteristics and wavelet coefficient quantization based on frequency characteristic, which severely damage the multimedia compressed image. Aiming at these problems, a compression algorithm of multimedia image is proposed based on improved wavelet domain sub vector, using improved LBG vector quantization method based on quantization compensation error to preprocess multimedia image, designing model from point to line, the low frequency part is selected from two dimension wavelet domain as the sub vectors, error compensation code method is adopted for the details of the sub vector in the wavelet domain to smooth multimedia image noise, two level wavelet transformation is utilized for N code book to extract the low-frequency coefficients, through the arithmetic coding to achieve multi-source information multimedia image compression and decoding, so as to recover recognition results. The experimental results show that, compared with the traditional wavelet transform image compression algorithm, the improved multimedia image compression algorithm proposed in the paper improves the quality of multimedia compressed image.
