In this report, we propose a structure transforming images with discrete wavelet transform (DWT) for image coding application. DWT is obviously an efficient tool. However, by using DWT, an image coding efficiency is
decreased when the image has much energy in high frequency region. Wavelet packet has been proposed to overcome the disadvantage, however it requires many computational costs. Therefore, we propose a structure, which overcome the disadvantage by using spatial characteristics in subbands without introducing many computational costs. The proposed method performs efficient results of image coding application with embedded coding algorithms. |
