Lattice Vector Quantization for Image Coding Using Expansion of Codebook
We present a method for image coding which uses expansion of basic codebook, based on energy of the vectors, for assigning lattice points to the incoming vectors. Two expansions of the basic codebook are used. Since in this method range or radius of the codebooks is based on the energy of the vectors of input image, for different test images we get different basic and expansion codebooks. If th...
متن کاملFast Image Artistic Style Learning Using Twin-Codebook Vector Quantization
Recently, the Twin-codebook Vector Quantization (TBVQ) has been developed for image colourization. It adopts two different but related codebooks in the encoder and decoder respectively, instead of the same codebooks used in traditional vector quantizers. In this paper, a novel image artistic style learning scheme is proposed based on TBVQ. During the learning process, the target image is first ...
متن کاملNovel codebook generation algorithms for vector quantization image compression
Novel algorithms for vector quantization codebook design are presented in this paper. Two basic techniques are proposed. The first technique takes into consideration specific characteristics of the blocks of the training sequence during the generation of the initial codebook. In this way a representative initial codebook is generated. Starting from a high quality initial codebook the iterative ...
متن کاملImage Vector Quantization for Interframe Coding Applications
In this paper, an interframe image coding via vector quantization (VQ) is considered. Here, we identify the moving vectors in each frame using a block matching technique. A prediction is estimated by searching in the direction of minimum distortion in the previous reconstructed frame, then the differential vectors are quantized via a modified VQ to achieve high compression. Simulations have sho...
متن کاملFast vector Quantization of Color Image Coding with Single Codebook based on Orthogonal Polynomials
In this paper, a new fast vector quantization encoding technique for transform coding of RGB color images that does not require a color coordinate conversion matrix is proposed. The proposed work directly applies the orthogonal polynomials transformation on the input image and transformed training set with reduced dimension is obtained for the vector quantization and hence the proposed work has...
