Abstract :
Applications of bounded error parameter estimation in the field of image compression are described. A bounded error parameter estimator is shown to improve the performance of an adaptive predictive compression scheme. The quantization of discrete cosine transform coefficients is viewed from a parameter bounding perspective and bounds for the coefficient quantization error are derived. They can be used to keep the reconstructed image sample quantization error within bounds
