This property is affected by many fiber performances and processing parameters, which makes its prediction difficult also. In this study, we predicted the hairiness of the cotton yarn in rotor spinning using the ANN model. On the basis of the results obtained, with help of ANN analysis, we can predict the hairiness of the cotton easily and accurately. The results show that the ANN model yields more accurate and stable predictions, which indicates that the ANN theory is an effective and viable modeling method.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"470 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114102136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And then, the structure and data organization of HSES were introduced, furthermore, the key data transfer tool was completed, that can transfer existing highway geometric design data in China to Land XML 1.0 data for the use of after-then safety evaluation. Thirdly, the modules of HSES were shown and explained. And details of the proposed models development and implementation for operation speed and crash prediction were described.

We propose a method of moving shadow detection based on local texture features integrated with linear characteristics. Firstly, an adaptive background model was built on the basis of RGB color information, and speedy moving target detection was based on the background subtraction. And then, do shadow detection through Hamming distance by using the texture information which described by improved LBP local texture operator. Finally, the judgement of linearity occur via the previous texture information for the further shadow detection. According to the experiment, this method succeeds in detecting shadows robustly and achieves real-time performance.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121676888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After adjusting the model, occupant head and chest injury curves and injury values such as HIC, T3MS and Thpc are got, which are close to test ones contrasted with the vehicle impact test. Then the injury estimate system of bus occupant in emergency brake is established and the model is used to compute the simulation of bus emergency brake with the assumption of assumptive approximate decelerate speed. Then different types of safety belts and cushion angles related to injury values are got. Simulation analyzing reveals that three-point safety belts can protect occupant better and augmenting the cushion angle can reduce occupants’ injury values.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114783015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By processing the sequence of the range images, the algorithm outputs trajectory and speed of each object during the period when he is in the detection region. The whole algorithm consists of two parts, which are the object detection and the object tracking. In the former, the multi-level thresholding method is combined with the Iterative Selforganizing Data Analysis Techniques Algorithm (ISODATA) to implement object segmentation. In the latter, Kalman Filter is applied to recognize and track moving objects. Experimental results demonstrated this algorithm is effective in object recognition and tracking, as well as robust in the applications.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124487636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
