متن کاملVector Quantization of Images Using the L 1 Distortion
| This paper considers the vector quantization of signals using the L1 distortion measure. The key contribution is a result that allows one to characterize the centroid of a set of vectors for the L1 distortion measure. A method similar to the LBG algorithm for designing codebooks has been developed and tested. The paper also discusses the design of vector quantizers employing the L1 distortion...
متن کاملDistortion-Limited Vector Quantization
This paper presents a vector quantization system that limits the maximum distortion introduced to a pre-selected threshold value. This system uses a recently introduced variation of the L 1 distortion measure that attempts to minimize the occurrences of quantization errors above a preselected threshold. The vectors are rst coded using the new distortion measure. The quantization error vectors i...
متن کاملSubband coding of images using vector quantization
Subband coding has proven to be a powerful technique for medium bandwidth source encoding of speech. Recently, some promising results have been reported on the extension of this concept to the source coding of images. In this paper, a new two-dimensional subband coding technique is presented which is also applied to images. A frequency band decomposition of the image is carried out by means of ...
متن کاملDecentralized Estimation using distortion sensitive learning vector quantization
A typical approach in supervised learning when data comes from multiple sources is to send original data from all sources to a central location and train a predictor that estimates a certain target quantity. This can be inefficient and costly in applications with constrained communication channels, due to limited power and/or bitlength constraints. Under such constraints, one potential solution...
