We propose a method for cross-fading of JPEG2000 encoded images. The main feature of the method is that memory usage with the cross-fading operation is lower than that of conventional methods. In this paper, firstly, problems on applying cross-fading operation to JPEG2000 compressed images are discussed. Then the method based on the code-block is proposed. The code-block is known as a coding unit of JPEG2000 coding system and it is defined as a rectangular region in DWT domain. Finally, we provide some simulations and also verify the effectiveness of the proposed method.
