This paper is focusing on the 3D reconstruction of synapses which is a branch of micro reconstruction of brain. Having analysed the structure of synapses, we first detect and locate them in serial sections with cascade AdaBoost algorithm, then optimize the shape of synapses by constructing suitable fitting functions and segment them with morphology processing method. Taking the connection of adjacent sections and synaptic extensibility in space into consideration, we complete the reconstruction of synapses which is based on the segmentation in serial sections. Actually all our works are based on the registration of serial sections.","PeriodicalId":260197,"journal":{"name":"2016 IEEE International Conference on Mechatronics and Automation","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121146125","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}

Behavioral results showed that response to bimodal audiovisual stimulus was significantly slower when an audiovisual stimulus was accompanied by a simultaneous visual cue than it was not accompanied. The fMRI results showed left premotor cortex was activated by unimodal visual stimulus accompanied with simultaneous visual cue. This result indicated a simultaneous visual cue provided reliable spatial information to visual stimulus, resulting in intramodal visual integration. Left inferior frontal gyrus, letft somatosensory association cortex and left supramarginal cortex were significantly activated by bimodal audiovisual stimulus accompanied with simultaneous visual cue. These activation regions indicated different roles were need for multisensory integration network.

Compared with Kalman filter, the weighted moving average filter has simpler algorithm structure, higher computational efficiency. Its convergence time is shorter than Kalman filter.

To solve the problems of lack of depth information in recognition based on 2D image and no enough obvious features used for recognition based on 3D point cloud, a novel approach of identifying individuals using 3D point clouds matching of finger vein and contour is proposed in this paper. A pair of vein images of a finger are captured under Near Infrared(NIR) light using our binocular vision device. The edge and vein contours of finger are extracted as features used for describe finger vein and then 3D point cloud of finger vein and contour is reconstructed though binocular vision technique. At last, personal identification based on matching results between template and reconstructed 3D point cloud using Iterative Closest Point(ICP) algorithm can be achieved. The experimental results show that proposed method can generate more discriminative features to represent 3D model of finger vein and contour so that the accuracy of matching is enhanced.","PeriodicalId":260197,"journal":{"name":"2016 IEEE International Conference on Mechatronics and Automation","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121044589","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}

In this paper, we design and implement an embedded controller, which is made up of two parts: upper layer ARM controller and lower layer DSP controller. The ARM controller, integrated with a WIFI module to facilitate remote control by PC, is responsible for gait planning and sensors information processing. The DSP controller is mainly designed to receive real-time control commands from ARM controller via serial peripheral interfaces (SPI) and communicate with motor drivers through Controller Area Network (CAN) bus. To achieve fairly accurate control of the quadruped robot, four force sensitive resistors (FSRs) and a gyroscope are used on the quadruped robot. The developed embedded controller has been employed to control the quadruped robot Biodog, built at our lab. Using Hopf-based Central Pattern Generator (CPG) algorithm, we conduct experiments on the quadruped robot Biodog to test the embedded controller. The results demonstrate the efficiency of our controller for the rhythmic quadruped locomotion.","PeriodicalId":260197,"journal":{"name":"2016 IEEE International Conference on Mechatronics and Automation","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127795108","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}
