摘要

Due to limitations of mobile environments, the handling of imagery is still problematic. This becomes especially apparent if two images are to be blended in order to create a smooth transition. As existing techniques fail to adapt to the restrictions of mobile environments, new ideas for the appropriate implementation of the blending are required. This publication proposes a new approach for the creation of transitions for mobile hardware. The foundation are the different features of the new image compression standard JPEG2000. The main properties used within the proposed strategy are the Discrete Wavelet Transform as integral part of the codec and the options for Random Spatial Access within the data-stream. Based on this, different options to blend contents of two images in JPEG2000-domain either in stationary as well as remote environments are introduced. A discussion of the results shows that this saves valuable computing power, is able to be applied to partial image data and achieves better visual results than traditional approaches. Thus, it is appropriate to apply the proposed approach to support the browsing of image sequences within mobile devices.
