Abstract
Due to hardware limitation, most interpolation method has been carried out by software and becomes an important research task. Various techniques have been proposed to improve the visual quality of interpolated quality. In addition, with a good interpolation, we can facilitate predictive image coding technique.Wavelets are being used in a number of different applications such as image enlargement and image compression. In order to benefit both applications, we propose a method to estimate high pass output from the low pass one. Using the predicted high pass output, we would be able to enlarge the image superior to other compared interpolation methods in many situations. Moreover, we use the predicted subband to wavelet image coder. It is shown that by using the proposed method, we can profit both image enlargement and its compression.
