The traveling salesman problem (TSP) in operations research is a classical problem in discrete or combinatorial optimization. It is a prominent illustration of a class of problems in computational complexity theory which are classified as NP-hard. Ant colony optimization inspired by co-operative food retrieval have been widely applied unexpectedly(More)
In order to realize integration of the social logistics resource and provide customized logistics services to the customers, this paper presents a regional logistics platform architecture based on cloud computing through systems analysis. Subsequently, a suggestion about adopting the mode of cooperative operation leading by the enterprise is provided(More)
In this paper, a robust gait recognition algorithm based on key frame and ellipse model is proposed, which solves the problems including finding key frames on discontinuous contour segmentation and accurate feature extraction on ellipse model. Firstly, a robust extraction algorithm of key fame is introduced, which makes detection of key fames easier and(More)

Cooling towers are a source of Legionnaires' disease. It is important from a public health perspective to survey industrial cooling towers for the presence of Legionella. Prospective surveillance of the extent of Legionella pollution was conducted at factories in Shijiazhuang, China between March 2011 and September 2012. Overall, 35.7% of 255 industrial(More)
Text superimposed on the video frames provides supplement but important information about video content. Recognizing artificial text embedded in video frames is very important and meaning for video indexing and retrieval. In this paper, an efficient approach of text extraction based on temporal information and mathematical morphology is presented. In the(More)
This paper describes an optical system for low-complexity optical image acquisition based on a single scanning MEMS mirror and a single photodetector. The overall aim of the research is to investigate techniques for image acquisition at electromagnetic wavelengths where the cost and/or technical maturity of detector arrays pose a limitation. In contrast to(More)
