Active vision system has been researched recently to address problems with saccade movement and real-time realization. The paper proposed the use of a hybrid system consisting of an object recognition model built with MobileNet SSD and an object tracker running Median Flow. This system has proven to work well in real-time application, with an average 15 frames per second and angular speed of 75 degree per second. The system remains stable and robust throughout all experiments. The final design is implemented to control movement of a transhumeral prosthesis through determining object of interest, calibrating wrist according to object position and choosing grip patterns with respective to object characteristics.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132413315","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 architecture design, an SP segmentation circuit that performs four iterations for whole image in one pass with four processing elements (PEs) is introduced. An SP-based stereo matching circuit is configured by serially connecting the same number of PEs as the maximum disparity, and performs parallel matching of all disparities for a left pixel, while suppressing memory access of the right pixel to 1 pixel / cycle.

This model comprehensively accounts for different terms that contribute to the gate capacitance such as insulator, centroid and quantum capacitance. It considers 1D confinement of electron, wave function penetration into the insulator and Fermi-Dirac statistics. It contains only one approximation that the shape of the wave function is independent of applied gate voltage and this approximation is taken care by adding perturbation term to the energy of sub-bands. We show that the model matches very well with data obtained from the 1D Poisson-Schrödinger solver for different channel thicknesses and materials.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134522588","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}

The detected angular velocity is used to control the ankle-pitch and roll motors for keeping the robot’s balance.
