Integration of Photometric Stereo and Shape from Occluding Contours by Fusing Orientation and Depth Data
In this paper, we have investigated the fusion of surface data obtained by two different surface recovery methods. In particular, we have fused the depth data obtainable by shape from contours and local surface orientation data obtainable by photometric stereo. It has been found that the surface obtained by fusing orientation and depth data is able to yield more precision when compared with the surfaces obtained by either type of data alone.

Image Stitching - Comparisons and New Techniques
This work describes the steps involved in the generation of a panoramic image, i.e., image acquisition, image registration and image merging. Different approaches for each of these steps are discussed and compared. The resultant images from image registration and image merging are quantitatively evaluated to provide an indication to the performance of the different methods. The methods provided in this work can be used to generate panoramic images for the use of interactive panoramic viewing of images, architectural walk-through, and other applications associated with the modelling of 3D environments.

Parallelization of Multiple Genome Alignment
In this work, we implement a genome alignment system which applies parallelization schemes to the ClustalW algorithm and the interface of database querying. Parallel construction of the distance matrices and parallelization of progressive alignment in the ClustalW algorithm are performed on PC-based Linux cluster with message-passing interface libraries. Achieved experiments show good speedup and significant parallel performance.

Query translation scheme for heterogeneous XML data sources
In order to formulate a meaningful XML query, a user must have some knowledge of the schema of the XML documents to be queried. The query will succeed only if the schema of the actual documents is consistent with the user's information. When a user queries a collection of documents collected from heterogeneous XML data sources, there is a high possibility that these documents do not all conform to the same schema assumed by the user, thus causing the query to fail. In this paper, we try to solve this query and data schema mismatching problem by proposing a query translation scheme. Without attempting to solve the general problem of schema integration, we present an inclusion mapping algorithm that decides how compatible the schema of the query and the schema of the target XML documents are. Based upon the compatibility, the query will be executed directly, or translated according to the target schema and then executed, or rejected.

Evolutionary interactive music composition
This paper proposes the CFE framework---Composition, Feedback, and Evolution---and presents an interactive music composition system. The system composes short, manageable pieces of music by interacting with users. The most important features of the system include creating customized music according to the user preference and providing the facilities specifically designed for producing large amounts of music. We present the structure as well as the implementation of the system and the auxiliary functionalities that enhance the system. We also introduce the auto-feedback test with which we verify and evaluate the interactive music composition system.

Factors in graphs with odd-cycle property
Abstract We present some conditions for the existence of a ( g , f )-factor or a ( g , f )-parity factor in a graph G with the odd-cycle property that any two odd cycles of G either have a vertex in common or are joined by an edge.

Representing the Semantics of Virtual Spaces
In the StarWalker virtual environment, users explore a shared semantic space and collaborate with concurrent visitors. The authors consider how StarWalker's design illustrates the potential of unifying spatial models, semantic structures, and social navigation metaphors in the development of multiuser virtual environments.
