It conducts offline analysis for record log file to recognize the record items with dependency relationship based on topological graph, and each thread only executes these record items in order in replay-runs.

With the development of depth cameras, color images combined with depth images can provide richer information for hand gesture recognition. In this paper, we propose a hand gesture recognition system based on the data captured by Intel RealSense Front-Facing Camera SR300. Considering that the pixels in depth images collected by RealSense are not one-to-one to those in color images, the recognition system maps depth images to color images based on generalized Hough transform in order to segment hand from a complex background in color images using the depth information. Then, it recognizes different hand gestures by a novel double-channel convolutional neural network containing two input channels which are color images and depth images. Moreover, we built a hand gesture database of 24 different kinds of hand gestures representing 24 letters in the English alphabet. It contains a total of 168,000 images which are 84,000 RGB images and 84,000 depth images. Experimental results on our newly collected hand gesture database demonstrate the effectiveness of the proposed approach, and the recognition accuracy is 99.4%.","PeriodicalId":331555,"journal":{"name":"2018 Eighth International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124543783","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}

Grid-based Motion Statistics (GMS) is a fast and ultra-robust image feature matching algorithm. However the correct matching rate and registration precision of GMS are relatively low. In order to obtain accurate aerial stitching images while ensuring high matching speed, an aerial image mosaic algorithm based on improved GMS is proposed in this paper. Firstly, we apply the ORB algorithm to extract and describe the feature points of the image. Then, GMS-based bidirectional matching is used to acquire the initial matching points. After that, false matches are rejected by constructing epipolar constraint. Finally, we use Random Sample Consensus Algorithm (RANSAC) to calculate the transformation model and fuse the aligning images by weighted average fusion algorithm. Experimental results show that the proposed algorithm has good matching accuracy and registration accuracy while maintaining a low matching time.","PeriodicalId":331555,"journal":{"name":"2018 Eighth International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123820770","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}

CPW feed is employed to enhance the impedance bandwidth of the proposed antenna. Similarly, implementation of fractal geometry in tuning stub is used for its miniaturization (20.98% for second iteration). In an attempt to further increase the bandwidth of the proposed antenna, Particle Swarm optimization (PSO) method is employed to optimize the proposed structure. The obtained results establish that the antenna functions in the 3.90 GHz to 15.82 GHz band.

This paper makes researches on the permanent magnet synchronous motor (PMSM) of an USV and characteristics of its composite ship-propeller load, and then proposes introducing model predictive control (MPC) to improve the dynamic performance of USV propulsion system further. The correctness and effectiveness of the design of the model predictive control USV propulsion system is verified through the Matlab/Simulink simulation analysis. In the case of ship-propeller composite load, simulation experiment results show that the PMSM propulsion system adopting MPC strategy can not only overcome the shortcomings of setting PI parameters difficultly, large speed and torque overshoots in dynamic processes, but also enhance both the anti-interference ability of USV propulsion system under complex sea conditions and the dynamic and static performance of the system.","PeriodicalId":331555,"journal":{"name":"2018 Eighth International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129978551","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 the design procedure, the joint commanded torque generated by a distributed fault-tolerant controller is filtered and compared with a filtered torque estimate derived from the nonlinear dynamic model of MRR based on joint torque sensing. Considering the motor output capacity, a novel performance index for providing the operation health conditions of an MRR joint is constructed by using the torque prediction error. The proposed scheme is shown to be able to monitor the health of the overall joint for MRR with any movement, which is essential for robots working in human environments.
