Vector Quantization Based Image Compression
An image compression method combining discrete wavelet transform (DWT) and vector quantization (VQ) is presented. First, a three-level DWT is performed on the original image resulting in ten separate sub bands. These sub bands are then vector quantized. VQ indices are Huffman coded to increase the compression ratio. Lloyd extended scalar quantization technique is used to design memory less vect...
متن کاملModified Vector Quantization Method for Image Compression
A low bit rate still image compression scheme by compressing the indices of Vector Quantization (VQ) and generating residual codebook is proposed. The indices of VQ are compressed by exploiting correlation among image blocks, which reduces the bit per index. A residual codebook similar to VQ codebook is generated that represents the distortion produced in VQ. Using this residual codebook the di...
متن کاملImage Compression Using Hybrid Vector Quantization
In this paper, image compression using hybrid vector quantization scheme such as Multistage Vector Quantization (MSVQ) and Pyramid Vector Quantization (PVQ) are introduced. A combined MSVQ and PVQ are utilized to take advantages provided by both of them. In the wavelet decomposition of the image, most of the information often resides in the lowest frequency subband. MSVQ is applied to significa...
متن کاملImage Compression Using Learned Vector Quantization
This paper presents a study and implementation of still image compression using learned vector quantization. Grey scale, still images are compressed by 16:1 and transmitted at 0.5 bits per pixel, while maintaining a peak signal-to-noise ratio of 30 dB. The vector quantization is learned using Kohonen’s self organizing feature map (SOFM). While not only being representative of the training set, ...
