The functions required for digital museum was revealed through this study. This term is the final year of this research project, Grant-in aid for scientific research. Results of this study are summarized as follows ;(1) We revealed that the reversibility, the progressibility and the scalability are important for the super high definition image application systems. In this study, we proposed a new scalable coding method based on an adaptive wavelet transform with lifting scheme. Moreover, simulation experiments using the verification model VM0 of JPEG-2000 are performed for super high definition images. (2) To preserve a three-dimensional item in the digital museum, it is necessary to take super fine photographs from various directions. Moreover, in order to represent an artwork faithfully, lossless coding is indispensable. To realize these functions we developed a new coding scheme that an archive the image group of an item taken from various directions, and enables free perusal accord … More ing to the user's demand. In our proposal, each frame can be regarded as the composition of the rotator and the background. The rotator part differs little by little with frame changes, and because this part corresponds to the information of an artwork, lossless coding is required for this part in every frame. Therefore, we first develop the extracting and coding method for the rotator, and then intra-frame prediction is utilized to code the image group for every other frame, and the remaining frames are coded exploiting the prediction from previous and succeeding frame, taking account of the rotation angle simultaneously. In the frame using the inter frames prediction, prediction from previous frame, prediction from succeeding frame, and intra frame prediction together contribute the data reduction. Thus, a frame is segmented into blocks and each block uses the three kinds of prediction alternatively.Moreover, another coding method is developed. A developed image is made by pasting multi-view point image set and approximated images are composed from this developed image using perspective projection and luminance correction method. Then the difference from the approximated image and the original image are encoded in a lossless manner.Simulations of both methods are performed and performances are evaluated. Less

通过本研究揭示了数字博物馆所需的功能。本学期是本研究项目的最后一年。研究结果如下：（1）揭示了超高清图像应用系统的可逆性、渐进性和可扩展性的重要性。在本研究中，我们提出了一种新的可分级编码方法的基础上，自适应小波变换与提升计划。此外，使用JPEG-2000的验证模型VM 0的超高清图像进行仿真实验。(2)为了在数字博物馆中保存三维物品，需要从各个方向拍摄超精细的照片。此外，为了忠实地表示艺术品，无损编码是必不可少的。为了实现这些功能，我们开发了一种新的编码方案，该方案将从各个方向拍摄的物品的图像组存档，并允许自由阅读雅阁 ...更多信息 满足用户的需求。在我们的方案中，每一帧都可以看作是旋转体和背景的合成。旋转器部分随着帧的变化而逐渐变化，并且由于该部分对应于艺术品的信息，因此需要在每帧中对该部分进行无损编码。因此，我们首先开发的提取和编码方法的旋转，然后帧内预测是用来编码的图像组每隔一帧，其余帧的编码利用预测从前一帧和后一帧，同时考虑旋转角度。在使用帧间预测的帧中，来自前一帧的预测、来自后一帧的预测和帧内预测一起有助于数据减少。该方法将帧分割成块，每个块交替使用这三种预测，并提出了另一种编码方法。通过粘贴多视点图像集来制作展开图像，并且使用透视投影和亮度校正方法从该展开图像合成近似图像。然后对近似图像和原始图像的差值进行无损编码，并对两种方法进行了仿真和性能评估。少
