DWT and CVQ based image coding for a low bit rate - Electronics Letters
A low hit rate coding method using the discrete wavelet transform (DWT), and classified vector quantisation (CVQ) is presented. An image is decomposed by DWT; then, the transformed image is encoded by CVQ. The proposed method allows the decoder to self-generate the class information for CVQ rather than requiring that it be received from the encoder. This results in improved compression performa...
متن کاملA Vq-style Adaptive Entropy Coder and Its Application to Lossless Image Coding
The VQ-style clustering algorithm proposed in this paper provides an optimal method for addressing the non-stationarity of a source with respect to entropy coding. This algorithm which is named Minimum-Entropy Clustering (MEC), clusters a set of vectors (where each vector consists of a fixed number of contiguous samples from a discrete source) using a minimum entropy criterion. In a manner simi...
متن کاملA Novel Vector Quantization Approach to Arabic Character Recognition
In this paper, a novel approach to Arabic letter recognition is proposed. The system is based on the classified vector quantization (CVQ) technique employing the minimum distance classifier. To prove the robustness of the CVQ system, its performance is compared to that of a standard artificial neural network (ANN)-based solution. In the CVQ system, each input letter is mapped to its class using...

We investigate the application of local Principal Com ponent Analysis PCA to transform coding for xed rate image compression Local PCA transform coding adapts to di erences in correlations between signal components by partitioning the signal space into regions and compressing signal vectors in each region with a separate local transform coder Previous researchers optimize the signal space parti...
متن کاملNew feature-based image adaptive vector quantisation coder
It is difficult to achieve a good low bit rate image compression performance with traditional block coding schemes such as transform coding and vector quantization, without regard for the human visual perception or signal dependency. These classical block coding schemes are based on minimizing the MSE at a certain rate. This procedure results in more bits being allocated to areas which may not ...
