Research ArticleOpen accessIn the abstractWheeled Mobile Robot Trajectory Tracking using Sliding Mode ControlAzza El-Sayed Bayoumi IbrahimThis paper introduces and discusses a control strategy for nonholonomic wheeled mobile robots. The models of the robots include the kinematic and dynamic equations of motion. Trajectory tracking control problem of parallel wheeled differential drive mobile robot is considered, where the robot should reach the final position by following a referenced trajectory for different initial conditions. A motion control strategy … …Journal of Computer Science, Vol. 12, Issue 1 · 12 Mar 2016 · 9,318 accessesView PDFCite
Research ArticleOpen accessIn the abstractFragment-based Visual Tracking with Multiple RepresentationsJunqiu Wang, Yasushi YagiWe present a fragment-based tracking algorithm that considers appearance information characterized by a non-parametric distribution and spatial information described by a parametric representation. We segment an input object into several fragments based on the appearance similarity and spatial distribution. Spatial distribution and appearance are important for distinguishing different fragments. We employee such information for separating an object from its background: … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 5 Jan 2016 · 7,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurements of Mitral Annular Displacement in 2D Echocardiography ImagesFaten A. Dawood, Rahmita W. Rahmat, Suhaini B. Kadiman et al.Mitral Annular Displacement (MAD) in echocardiography has been described as a variation in mitral annulus position between the end-diastolic and the end-systolic in a complete cardiac cycle. It could be used as a rapid and reproducible method of determining the LV global systolic function and could be an easily detectable index for wall motion abnormalities. In this study, a computational … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 4 Jul 2015 · 6,850 accessesView PDFCite
Research ArticleOpen accessIn the abstractTRACKING THE POSITION OF MULTIPLE HUMAN GESTURES USING CONTOUR MAPPING ALGORITHMT. S. Arulananth, T. Jayasingh, S. RaviThis study relates to a method for determining the position variation (for example a moving object, facial gesture tracking) using markers. The movement is determined based on the periodic frames captured using a camera. The experimental results show that this algorithm can accurately segment human movements from complex background and can greatly reduce the computational workload with less storage memory, … …Journal of Computer Science, Vol. 10, Issue 10 · 22 May 2014 · 6,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Fuzzy Logic Control with Input Shaping for Input Tracking and Sway Suppression of a Gantry Crane SystemM. A. Ahmad, Z. MohamedProblem statement: Most of the common gantry crane results in a sway motion when transporting the load as fast as possible. In addition, precise cart position control of gantry crane must required a zero or near zero residual sway. Approach: In this study, the development of hybrid control schemes for input tracking and anti-sway control of a gantry crane system … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,057 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMultiple Vehicle Tracking using Adaptive Gaussian Mixture Model and Kalman FilterFandy Setyo UtomoBased on data from the Central Statistics Agency (BPS) of the Republic of Indonesia in catalog Crime Statistics in 2014, the number of crimes of theft of motor vehicles has increased since 2010 until 2013. Recorded in 2013 the number reached 42.508 cases of theft. In this study, we made a prototype application using Adaptive Gaussian Mixture Models algorithms and … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 7,375 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAutomatic Detection of the End-Diastolic and End-Systolic from 4D Echocardiographic ImagesAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.Accurate detection of the End-Diastolic (ED) and End-Systolic (ES) frames of a cardiac cycle are significant factors that may affect the accuracy of abnormality assessment of a ventricle. This process is a routine step of the ventricle assessment procedure as most of the time in clinical reports many parameters are measured in these two frames to help in diagnosing and … …Journal of Computer Science, Vol. 11, Issue 1 · 25 Aug 2014 · 8,500 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMOTION DETECTION USING THE SPACE-TIME INTEREST POINTSInsaf Bellamine, Hamid TairiSpace-Time Interest Points (STIP) are among all the interesting features which can be extracted from videos; they are simple, robust and they allow a good characterization of a set of regions of interest corresponding to moving objects in a three-dimensional observed scene. In this study, we show how the resulting features often reflect interesting events that can be used for … …Journal of Computer Science, Vol. 10, Issue 5 · 17 Jan 2014 · 6,643 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMorphing Mechanisms Part 1: Using Iterative Learning Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis study introduces the concept of morphing mechanisms. Mechanisms are normally designed for specific operating conditions and once they are built one may wish to use them under different operating conditions. In some cases, a mechanism may be imperfectly fabricated and one would like to get the intended ideal performance. In these cases, instead of designing, fabricating and replacing the … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,837 accessesView PDFCite
