We use two pairs of rectangle coils to generate rotary magnetic field. The capsule with a permanent magnet rotates along with the magnetic field. With the help of the whirl on its surface, the capsule can move in a certain direction. From the experiment, we find out the critical frequency of rotation when the capsule can rotate smoothly. Besides, we improve the existed mathematical model of the coil's magnetic field. The thickness of the coils is taken into account. Finally, MATLAB simulation experiment is carried out to analyse the relation of the coils' sizes and the character of magnetic field distribution. The result shows the intensity and uniformity of the magnetic field cannot be optimal simultaneously, so different weight should be set to determine coils' sizes in practice.","PeriodicalId":299418,"journal":{"name":"2011 IEEE International Conference on Information and Automation","volume":"646 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416864","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}

We use SIFT features and the bag of features method to represent and recognize building images. Four distance methods are compared to estimate the distance between query image and those in database, namely L1-norm, L2-norm, KL-divergence and χ2 distance. We calculated ROC curves to compare these methods. Experimental results exhibit that χ2 distance has the best performance. Our system is fast enough for realtime application and its accuracy is satisfactory under the experimental environment.","PeriodicalId":299418,"journal":{"name":"2011 IEEE International Conference on Information and Automation","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124148480","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}

SIFT descriptor is used to select key points of faces in the database including seventy people with nine poses in the first stage. Then according to the feature of a test face, matching algorithm is applied to find its candidates from the database and defines some criteria to convince the final matching result in the second stage. If satisfactory results can not be gained in the second stage, the 3D rotation method will be triggered and it makes a secondary decision by normalizing the depth information of the faces.
