Image De-Quantization Using Plate Bending Model

Cloth Deformation Modelling Using a Plate Bending Model

Modelling and simulation of cloth deformation are of great importance in computer graphics and engineering applications. Although many models have been developed, problems still exist. No model so far can accurately describe both motion and deformation of cloth in a unified equation. And the equations for the in-plane deformation of cloth have yet to be developed. In this paper, a model for bot...

Vector quantization for license-plate location and image coding

License-plate location in sensor images plays an important role in vehicle identification for automated transport systems (ATS’s). This paper presents a novel method based on vector quantization (VQ) to process vehicle images. The proposed method makes it possible to perform superior picture compression for archival purposes and to support effective location at the same time. As compared with c...

Medical Image Compression Using Vector Quantization and Gaussian Mixture Model

Codebook design for vector quantization could be performed using clustering technique. The Gaussian Mixture Modeling (GMM) clustering algorithm involves modeling a statistical distribution by a mixture (or weighted sum) of other distributions. GMM has proven superior efficiency in both time and accuracy and has been used with vector quantization in some applications. This paper introduces a med...

Model-Based Color Image Sequence Quantization y

We investigate the display of color image sequences using a model-based approach to multilevel error di usion. We extend Bouman and Kolpatzik's technique [1] for design of an optimal lter to the temporal dimension. Our model for the human visual system accounts for the spatial and temporal frequency dependence of the contrast sensitivity of the luminance and chrominance channels. We observe an ...
