Research Status£º

My research interests include obile Graphics Rendering, Mobile Augmented Reality,visualization, medical image processing, and wavelet analysis and its application, image-based modeling and rendering (IBMR)

I have done various visualization research and application projects on terrain data, power system data, dental cast, visual human, and lunar surface and solar wind ion data provided by Chang'E-1 Exploration Satellite. I have developed a computer-aided reconstructing and measuring system of 3D Dental cast with circular scanning data; I have presented a 3D, multiresolution, approximate lunar surface model based on a subdivision-surface wavelet, as well as efficient tools for rendering the three-dimensional surface at speeds approaching real-time interaction in a general Personal Computer (PC) environment; I have proposed 3D visualization method of solar wind ion data from the Chang¡¯E-1 exploration, and this visualization method is integrated into an interactive visualization analysis software tool named vtSWIDs, developed in MATLAB, which enables researchers to browse through numerous records and manipulate the visualization results in real time. I also developed a view-dependent progressive transmission and rendering system for Lunar Model based on Bicubic Subdivision-surface Wavelet. An interactive visualization for lunar model with texture and labels has been developed. Three-dimensional visualization for power system data are realized.

In recent years, supported by National 863 High-Tech Program and National Natural Science Foundation of China, I have been investigating post-processing issues of OCT images, such as image classification and layer detection. I have proposed a novel OCT image classification method with local texture feature and EMD (Earth Mover's Distance). I also have developed effective automated techniques of measuring pearl thickness, cornea thickness, anterior chamber depth, and retina thickness. I have developed an automated measuring system of anterior contour with VC++, which is accurate, robust and real-time.

Wavelet analysis is one of my favorite research fields. In particular, I focus on wavelet construction, fast algorithm of wavelet transform, and its applications in geometric modeling and image processing. I began to study wavelet and its applications in geometric modeling and volume visualization in 1996 when I was a Ph.D. student in Beihang University. Then, as a postdoc in Tsinghua University, I shifted my focus to problems of symmetric lifting factorization, fast implementation of biorthogonal wavelet transform, and its application in DEM compression. In 2005, my book-Wavelet Analysis and its Applications-was published. In recent years, I mainly investigate the algebraic construction method of orthogonal and bi-orthogonal wavelet filters, the lifting construction method of dyadic wavelet, and two-dimensional stationary dyadic wavelet transforms, the construction of dyadic wavelet that equal its reconstruction wavelet . Recently, I applied subdivision surface wavelet to lunar 3D modeling and visualization.

In IBMR, I have proposed an IBR algorithm based on Weak Perspective model, a 3D recovery method of specular surface using color highlight stripe and light source coding, a structured light inspection method on specular surfaces using Quaternary Coding, and an efficient algorithm to reconstruct 3D surface with two image pairs based on Helmholtz Reciprocity.

My research contributions are as follows:

1) Based on the data from the Chang¡¯E-1 exploration, I presented a new method to represent and visualize 3D lunar surface model so that it can be viewed interactively in a general PC; I also proposed a novel 3D visualization method of solar wind ion data and further developed a real-time visualization tool. Furthermore, view-dependent progressive transmission and remote browsing system for lunar model, and interactive lunar model with texture and labe are developed.

2) I have proposed a novel method for automated classification of OCT images based on local features and earth mover's distance (EMD), which has been published in Journal of Biomedical Optics in 2009. It is the first work to use local features for solving the problem of OCT image classification. I have also presented effective method for automated contour extraction of anterior OCT images and novel 3D segmentation method for retinal 3D OCT layer detection. Now two patents have been applied.

3) For bi-orthogonal finite filters, I proved that there exists one and only one symmetric factorization of the polyphase matrix, and that the symmetric factorization can be determined directly and efficiently. Symmetric implementation and matrix representation of biorthogonal wavelet transforms are also given. These results have been used in the compression of terrain data. Recently, I focus on the study of dyadic wavelet theory. First, I proposed a constructive method of lifting constructing spline dyadic wavelets with arbitrary numbers of vanishing moments. Secondly, I have proposed a two-dimensional stationary dyadic wavelet transform and its fast algorithm, which, different from classical two-dimensional dyadic wavelet transform, is essentially an extension of two-dimensional stationary wavelet transform for orthogonal/bi-orthogonal wavelet filters. Finally, for spline dyadic wavelet that equals its reconstruction one, I have proved that there are no finite spline high pass filters possessing symmetry with respect to 0 or 1/2. It further shows that there exist infinite spline high pass filters possessing symmetry with respect to 0 or 1/2. These theories and algorithms have great potential in advancing research and application of dyadic wavelet. Based on these results, three papers have been published in International Journal of wavelets, multiresolution and information processing, one paper in International Journal of Computer Mathematics and another one paper in ICIP¡¯04.
