This paper proposes a real-time method for 3D eye performance reconstruction using a single RGBD sensor. Combined with facial surface tracking, our method generates more pleasing facial performance with vivid eye motions. In our method, a novel scheme is proposed to estimate eyeball motions by minimizing the differences between a rendered eyeball and the recorded image. Our method considers and handles...
The University Ideological and political counselors as ideological communicators, has important role in the social stability and unity, with the country of thought right unified attention, more and more researchers take this as an important research project, played a very good effect, but with the diversification of education trend, how to carry out more quantitative analysis of Ideological and political...
In China the low carbon electricity is one of the key issues of its sustainable development. Although the power structure adjustment and non-fossil energy development have great progress during the “12th Five Year Plan” period, there are still some outstanding problems about the coordinated development of fossil energy power generation and non-fossil energy power generation. So based on the analysis...
The objective of this initial study is to investigate acoustic microscopy as a tool to elucidate the relationship between microscopic structural properties of the sclera and its macroscopic mechanical properties in healthy and myopic conditions. Excised sclera from both eyes of one guinea pig were scanned with a custom-built scanning acoustic microscope (SAM). Prior to euthanasia and excision, the...
A miniaturized vortex-induced vibration (VIV) fluid energy harvester is proposed. The theoretical background of this working principle is studied. A fluid-structure interaction simulation is carried out to optimize the structure of the energy harvester. As result, the conversion efficiency is significantly improved, which is experimentally confirmed. The demonstrators are working in air flow already...
Myopia is caused by excessive axial eye length, which results in images focused in front of the retina. High (pathologic) myopia can lead to irreversible vision loss. The anatomic changes underlying excessive eye elongation likely occur in the eye wall (sclera), which becomes more flexible than in non-myopic eyes. In the present study, we employed a form-deprivation (FD), guinea pig myopia model and...
As solar with the highest development potential, photovoltaic (PV) generation increases fast in installation and grid connection with continual mature and improvement of relevant technique. However, the inherent uncertainty of PV generation has direct influence on the stable operation and consumption potential of its connected system, and this has become one of the key problems relating to continuous...
This paper starts from the changes of diesel price in China, and then makes the seasonal adjustment and trend decomposition based on the diesel prices time series data from December 2009 to January 2013 to predict the price of diesel by an exponential smoothing method. The results show that the diesel price (10 #) in China still has the rising trend and the predicted diesel (10 #) prices will reach...
As the main emitter of CO2, power sector is becoming the primary focus for carbon reduction. However, existing researches mainly focus on power generation side, for example, renewable energies and nuclear, the role grid plays is often ignored. This paper assesses carbon reduction impact of cross-region power transmission in China by establishing a multiregion Integrated Resource Strategic Planning...
The quantitative analysis on the mobility behaviors of subcellular structures is essential for understanding eukaryotic cells establishment and maintenance. Tagged by the fluorescent marker proteins, the subcellular structures are visualized under the modern microscope. In this paper, we propose a graph model to formulate the tracking problem on fluorescent marker protein. By minimizing the energy...
To address the technical problem that hinders the practical application of digital watermarks, an implementation method of digital watermarking against the geometric attacks with the lifting wavelet transform (LWT) is proposed. Based on the characteristics of the wavelet transform sub-bands, one of the wavelet sub-bands of the carrier image is divided into four blocks. This method is combined with...
Malignant melanoma is among the most rapidly increasing cancers in the world. Image border detection is often the first step to characterize skin lesion for the follow-up computer-aided diagnosis. Existing approaches lack robustness in the face of dermoscopy images varying in size, color, texture, and structure. In this paper, a generalized Markov random field (MRF) framework is proposed to fuse the...
In this paper, we propose a predictive coding approach to identify microvessel subimages using Single-Opponent (SO) signal. First, we simulate the signal from SO neurons in the positive red and negative cyan channel to segment microvessel regions. Second, the SO signal is convolved with a Laplacian of Gaussian (LoG) filter and then processed in a predictive coding and biased competition (PC/BC) neural...
Color quantization is an important operation with many applications in graphics and image processing. Clustering algorithms have been extensively applied to this problem. In this paper, we propose a simple yet effective color quantization method based on divisive hierarchical clustering. Our method utilizes the commonly used binary splitting strategy along with several carefully selected heuristics...

Recently the sparse coding approaches have been successfully applied to solve the image classification problems. However, the classification of microvessel regions from histopathology still rely on the hand designed low-level features. In this paper, we propose a novel method to classify region of microvessel by applying sparse coding on biological signals. The Single- and Double-Opponent signals...
Malignant melanoma is among the most rapidly increasing cancers in the world. Image border detection is often the first step to characterize skin lesion for the follow-up computer-aided diagnosis. As the existing segmentation techniques tend to find the sharpest pigment change in the dermoscopy images, the detected lesion borders are mostly contained inside the borders delineated manually by the dermatologists...
In order to change the current disadvantages of traditional ship maintenance concept, this article plans to apply the technical method of prognostics and health management (PHM) to improve equipment maintenance program and repair schedule. In the meantime, this thesis takes account into the example of the dredger power system of the Waterway Bureau to establish the PHM optimized system of life cycle...
In this paper, we proposed a method for microvessel density estimation based on color region annotation. First, the pericytes and endothelial cells of the microvessel are modeled in the RGB color space by minimum error thresholding. Second, the connected component labeling method is used to extract microvessels in the neighboring red and brown color regions. Third, the microvessel density is estimated...
In this paper, we proposed a novel approach towards the pose recognition of giant pandas based on the gradient shapes. The proposed approach is implemented in three main steps. First, the gradient contour is extracted by filtering the internal pixels in the gradient image. Second, a novel region partition method is used to measure the body weight of giant panda in different image directions. Third,...
