Due to the urgent requirements of mass data processing in the field of astronomy, with the advent of network grid computing technique, scientific workflow technique was presented and quickly adopted for distributed astronomic data processing. However, current existing scientific workflow systems are too complex and enormous in system deploying and system manipulation. Few people can master it in short period. In this paper, we presented a lightweight scientific workflow system, CSWF, which is specially designed for astronomy. All required fundamental functions, such as task customization, data movement, provenance and task re-run mechanisms, are fully implemented. Comparing with the existing scientific workflow system, C-SWF provides many useful features such as simple, high performance and easy to deploy in order to meet the requirements of astronomers. © 2009 IEEE.

In order to improve the imaging quality of conventional laser photography, this study proposes a new system for colored pulse laser photography to obtain high speed color microscopic imaging. Based on the RGB synthesis technique, three channels of red, green, and blue images are acquired from three cameras with three independent laser light sources. Then, a high quality color image can be obtained by assembling the monochromatic images with the image realignment and color calibration processes. The experimental results show that the proposed system can achieve a high quality colored pulse photography. © 2009 IEEE.

The goal of the research on ontology framework for content-based 3D model retrieval is to develop a rich set of 3D model semantic representation so that both humans and machines can generate and understand model descriptions and processing for fast efficient retrieval from model collections. The purpose of ontology development for content-based 3D model retrieval is intended to describe model information regardless of storage, feature extraction and creation. The ontology includes the information on media features, low level visual descriptors, non media features of 3D model and their relationships. It is implemented in protege 3.1.

A semantic annotation method for web database query result which is under the condition of uncertain schema information is proposed in this paper by adopting the reinforcement learning method. Using domain ontology to annotate the query result, this paper takes the mapping between domain ontology and query result as a process of finding the best strategy. By training the numeric attribute value, we can find the best strategy to match and then annotate the query result. By collecting web databases from different domains, the experiments indicate that the approach proposed can annotate the web database query result properly and improve the efficiency of annotating. ©2009 IEEE.

The equalization-cancellation (EC) model has been extensively studied for expressing binaural masking level difference (BMLD) in psychoacoustics. Few research focuses on applying this psychoacoustic model to speech processing applications, such as speech enhancement. In this paper, we propose a two-stage binaural speech enhancement with Wiener filter (TS-BASE/WF) based on the EC model. In this proposed TS-BASE/WF, interfering signals are first estimated by equalizing and cancelling the target signal based on the EC model, and a time-variantWiener filter is then applied to enhance the target signal given noisy mixture signals. The main advantages of the proposed TS-BASE/WF are: (1) effectiveness in dealing with non-stationary multiple-source interfering signals;(2) success in localizing the target sound source after processing. These advantages were confirmed by comprehensive experiments in different spatial scenarios in terms of speech enhancement and sound localization. ©2009 IEEE.

Image Registration Using Object Shape's Chain Code

Image Registration Using Object Shape's Chain Code

Congress on Image and Signal Processing, CISP

This paper focuses an efficient image registration method based on image features. Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. This approach uses four basic steps of image registration procedure; namely, feature detection, feature matching, mapping function design, and image transformation and re-sampling. In this paper, object shape of images has been considered as an important feature for image registration. Initially, a process to obtain the unique chain code for each shape of images, which is invariant to translation, scaling and rotation, is generated. Using this unique chain code of shape representation, the translation, scaling and rotation of two different images has been calculated. Finally, the image registration has been done based on the unique chain code for each shape of the same image. The major goal of this paper is to register two or more different images of the same scene using object shape's chain code.

Based on the survey in the field, wavelet theory was adopted to analyze experimentally the distribution characteristics of Leymus chinensis vegetation coverage, on different scales in a 1000-meter-long sample belt. A suspending problem in studying simultaneously the vegetation pattern scale, intensity and grain on different scales was solved according to the analysis of projection figure of wavelet transform on different scales. This leads to find the feature that changes of vegetation pattern on different scales are consistent with fractal characteristics.

The domain knowledge has a direct impact on the result of question - answering (Q & A) in the restricted domain Question Answering System (QA). In this paper, a method of answer extraction for domain Chinese question-and-answer (Q&A) is proposed, which based on the analysis of interrogative sentence and the answer type, carrying on the text retrieval with the help of the domain knowledge and obtaining the relevant paragraphs of the question as the candidate answer. For the question of numeral or list entity type, extracted the question center related domain entity as the answers by adopting the naming entity recognition. For the definition questions, the sentences or paragraphs with higher relevance can be extracted to become the answer based on the relevance ranking between the candidate sentences or paragraphs and questions by combined the computing method of keywords weighting and the method of semantic similarity between the sentences and questions. Experimented on the answer extraction in Yunnan tourism domain, the results show that more remarkable effects have been achieved by adopting the method of answer extraction from domain Chinese question-and-answer. © 2009 IEEE.
