This paper focuses on basic geometric and topological access methods, and computational operations implemented by various data objects. It covers such methods as inter-slices point matching, stream slices, sorting of octree blocks, cell operations and experimental results. At first, this paper discusses in detail the feature points matching of inter-slices. Then it introduces stream slices eigenfields and octree data structures theories. Next, it discusses cell operations and its data structure. Finally, it shows an experimental result. The innovations in the paper is the data structure of slices feature and cell feature, and the feature matching methods owns the properties both quickly and exactly.

Digital watermarking has been proposed for the copyright protections of multimedia products. In this paper, a robust and blind watermarking scheme is presented. The concept of communication with side information is applied at the encoder to improve the probability of detection within acceptable fidelity, while the template matching technique is employed to estimate the undergone attacks in attacking channel. This scheme is optimized by the optimal design of the encoder to match with the media content and the decoder to adapt to the attack channel state. Experiments show that our method is robust against some common attacks such as filtering, compression, rotation, scaling, cropping and translation. It can be applied to both color and gray images.

An improved approach for JSEG is presented for unsupervised segmentation of homogeneous regions in gray-scale images. Instead of intensity quantization, an automatic classification method based on scale space-based clustering is used for nonparametric clustering of image data set. Then EM algorithm with classification achieved by space-based classification scheme as initial data used to achieve Gaussian mixture modelling of image data set that is utilized for the calculation of soft J value. Original region growing algorithm is then used to segment the image based on the multiscale soft J-images. Experiments show that the new method can overcome the limitations of JSEG successfully.
