Direct Volume-Rendering (DVR) is usually used in medical volume visualization, DVR images tend to be over-loaded with the content (blurred images). Thus, in many practical applications simpler techniques which do not rely on complex transfer functions are employed. For example, Maximum Intensity Projection (MIP) which depicts the maximum value along each viewing ray. In this paper, we improve the Illustrative context-Preserving volume Rendering based on Visualization Toolkit (VTK). In our method, it can simultaneously visualize interior and exterior structures while preserving clear shape cues. The main limitation of MIP is that it cannot adequately depict the spatial relationships of overlapping tissues. An approach has been proposed to eliminate this drawback: Local Maximum Intensity Projection (LMIP). LMIP is an extended version of MIP. LMIP selects the first local maximum value encountered that is larger than a pre-selected threshold value along an optical ray from the viewpoint in the viewing direction. In this paper we propose an improved local maximum intensity projection. An appropriate threshold and shading are computed in this improved method. We show that the improved method is a useful technology in volumetric dataset visualization. Keywords-direct volume rendering; MIP; LMIP; Shading

Based on the modified Ginzburg-Landau-Devonshire theory, the behavior of a ferroelectric film consisting of two different materials with an interface parallel to the spontaneous polarization is studied. The results show that for the composite ferroelectric film properties (transformation temperature, pyroelectric coefficient, etc), the Curie-temperature difference between two bulk materials is sensitive influencing factor and the change of the thickness of the transition layer has little influence.

One of the main challenges faced by the current face recognition techniques lies in the difficulties of collecting samples. In the situation of law actualizing, passport or status validating, only one sample per person is available. Unfortunately, many reported face recognition techniques rely heavily on the size and representative of training set, and most of them will suffer serious performance drop or even fail to work if only one training sample per person is available to the systems. Such a task is very challenging for most current algorithms due to the extremely limited representative of training sample. In this paper, the two-directional 2DPCA (BDPCA) is developed to attack this problem. The block weighted two-directional 2DPCA (MWBDPCA) is proposed for efficient face representation and recognition. Beside this, the fuzzy theory is applied to classification. Experimental results on ORL and a subset of CAS-PEAL face database show that the method presented achieves even higher recognition accuracy.

A new framework of image encryption via voice feature is proposed. Voice data is preprocessed and the MFCC coefficients are firstly calculated on each sub-frame; an iterated vector quantization is then applied on the MFCC data to obtain the key to image encryption and decryption. Image encryption and decryption is done in the frequency domain with a simple XOR operation. Due to the uniqueness and long length of the encryption key, along with the frequency domain encryption, the safeness of the whole system is assured.

The restoration of damaged images or the removal of shielding materials in a given image is well known as image completion. An important method is the exemplar-based image completion, which propagates pixel information in the source region into the missing region. Firstly, we compute the filling priority of unknown pixels based on the color and structure information, and determine the patch whose center pixel has the highest priority. Then, find an optimal patch throughout the candidate region surrounding the missing region with SSD. Based on this method, this paper proposes an approach to address the balance problem between image completion quality and efficiency. In cultural relic preservation, our method can assist restorer to recover the damaged old pictures efficiently. The experimental results demonstrate this method can complete both texture and structure images in a visually pleasing manner. Keywords-Image completion; Missing region; Priority; Cultural relic preservation

With an increasingly rich of the remote sensing data, how to extract meaningful surface information from the mass of remote sensing data has become a problem pressed for solution. Using the experts classification method, digital elevation model and the generated slope and aspect information as expert-assisted classification parameters, land use types of Guangzhou city are classified. The results show that the participation of more variable information such as elevation and slope can prevent the frequent occurrence phenomenon of same object with different spectra and different objects with same spectrum in the remote sensing classification effectively eliminate the impact of terrain. Consequently, effectively improve the accuracy of remote sensing image classification. Both accuracy of types and precision of the area, experts classification has the higher precision than the maximum likelihood supervised classification, provides an effective way to the land use classification for the complex terrain region.

Objective: In order to analyze the effects of Natural Cerebrolycin (NC) on the gene expression profile of Mesenchymal Stem Sells (MSCs), the feasibility of NC's clinical use for Alzheimer's Disease(AD)and the mechanism of its gene molecular Pharmacodynamics were studied. Method: The MSCs of rats were isolated and purified by whole bone marrow adherence and adherence screening method, the homology of the cells was analyzed by immunocytochemistry staining technique. The differential expression genes of MSCs treated with NC were analyzed by Affymetric whole genome gene chip analysis method. Result: Rat MSCs of higher purity (more than 90%) was acquired. After MSCs were treated with NC, 45 differential expression genes were displayed, the expressions of 21 genes among them were up-regulated (FC≥2) and the expressions of 24 genes were significantly down-regulated (FC≤-2).These genes included the genes participate in TGFβ / BMPs, Hedgehog, Bmp and Wnt signal transduction pathways that have relations with cell differentiation &development and /or nervous system function, and learning and memorizing functions, the genes of Ras and G protein-coupled receptor signaling pathways that have relations with cell growth and proliferation and apoptosis, and the genes of MAPKKK cascading. Conclusion: NC's anti-AD pharmacodynamic mechanism of molecular genes could have relations with numerous gene expressions of some signal transduction pathways, which participate in regulating nerve cell differentiation and development, nervous system function, functions of learning and memory, and common cell functions of growth, differentiation, proliferation and apoptosis.
