Abstract：Several neighboring pixels based prediction schemes were proposed by exploiting the statistical relationship between pixel distance and correlation.And an edge-adaptive predictive VQ scheme was proposed for images containing distinct edge characteristics.Simulations demonstrate the improved predicting accuracy and coding performance of the proposed predictive VQ algorithms for image coding applications constrained at a low computational complexity level.
