Abstract: In order to achieve a large quantity of data images on the network of rapid transmission，it must carry out its high compression.Now generally uses more advanced wavelet compression method，However，the use of compressed data to reconstruct the image with the original images than the obvious differences.To reduce the distortion of this，the beginning of this article proposes an effective allocation model based on the performance optimization method；To achieve such a rapid and low complexity of the distribution，and it proposes a semiregular mesh geometry coding related to the reconstruction of the mean square error of approximation.The experimental results show that the model-based allocation process will be similar to the above method results as a small distortion can be improved wave encoder performance，improve coding gain，and thereby achieve without lowering the rate of image compression to improve the image quality.
