Abnormal activity recognition using spatio-temporal features

Chathuramali, KGM; Ramasinghe, S; Rodrigo, BKRP [Conference-Abstract]

Abnormal activity detection plays an important role in many areas such as surveillance, military installations, and sports. Existing abnormal activity detectors mostly rely on motion data obtained over a number of frames ...
Action recognition using a spatio-temporal model in dynamic scenes

Chathuramali, KGM; Rodrigo, R [Conference-Abstract]

Action recognition in a video plays an important role in computer vision and finds many applications in areas such as surveillance, sports, and elderly monitoring. Existing methods mostly rely on stationary backgrounds. ...
AugLAC - Generic framework for augmented location aware commerce

Gunatunge, EMP; Hewagama, HYM; Hewawalpita, SGS; Perera, I; Udara, YBN

In this paper we present AugLAC, a framework which integrates common features of location aware services, ecommerce and augmented reality into a single infrastructure for the development of location aware mobile ...
DC Motor inertia estimation for robust bilateral control

Perera, GVAGA; Pillai, MB; Abeykoon, AMHS [Conference-Abstract]

Identification of system parameters of a small DC motor is a complex and challenging task. This research proposes a disturbance observer (DOB) based novel Change of Inertia Observer (CIOB) to estimate the moment of ...
Extensible video surveillance software with simultaneous event detection for low and high density crowd analysis

Hettiarachchi, AL; Thathsarani, HO; Wickramasinghe, PU; Wickramasuriya, DS; Rodrigo, BKRP [Conference-Abstract]

Manual analysis of large volumes of video surveillance footage stemming from the widespread deployment of security cameras is error prone, expensive and time consuming. Despite the commercial availability of software for ...
Position based static friction estimation for DC motors using dsturbance observer

Abeykoon, AMHS; Chinthaka, MKCD [Conference-Abstract]

Estimation of friction is not considered necessary in motion control systems when the precision is not a major concern. Effects of the frictional components could be ignored for small friction: motor torque ratio DC ...
Recognition of Badminton strokes using dense trajectories

Ramasinghe, S; Chathuramali, KGM; Rodrigo, BKRP [Conference-Abstract]

Automatic stroke recognition of badminton video footages plays an important role in the process of analyzing players and building up statistics. Yet recognizing activities from broadcast videos is a challenging task due ...
Redundant upper limb exoskeleton robot with passive compliance

Gunasekara, jmp; Gopura, RARC; Jayawardena, TSS [Conference-Abstract]

Enhancing physical Human-Robot Interaction (pHRI) is an important design aspect in upper limb exoskeleton robots. The level of manipulation provided by an exoskeleton robot has a significant effect to perform daily tasks. ...
Review on bilateral teleoperation with force, position, power and impedance scaling

Perera, GVAGA; Abeykoon, AMHS [Conference-Abstract]

Scaling is a technique used to transfer the dynamic motion properties of a remote device (slave robot) to the operator (master robot) or vice versa. This is a challenging task in terms of force, position, power, and ...
Simulation of active vibration suppression using internal motor sensing

Abeysiriwardhana, WASP; Abeykoon, AMHS [Conference-Abstract]

Suppression of unnecessary vibration is an important aspect in control system design. Passive, semi active, and active suspension systems are used in vehicles to suppress vibrations and theoretically active suspension ...
Simulation of enhanced force limiting gripper for bilateral teleoperation

Ruwanthika, RMM; Abeykoon, AMHS [Conference-Abstract]

This paper proposes an enhanced force limiting gripper to avoid object deformation when it is in contact with the slave due to excessive forces imposed by the master operator in bilateral control. The force lock protects ...
Sound localization : human Vs. machine

Jayaweera, WGN; Jayasekara, AGBP; Abeykoon, AMHS [Conference-Abstract]

The Human shows a remarkable capability in localizing a sound source and navigating towards it. In the current context of robotic applications, machinery models have been developed, so that they can be used in sound source ...
Study on impact of wind power park integration on weak power systems : a case study on Mannar Wind Park in Sri Lanka

De Silva, OSD; Dasanayake, VIP; Rodrigo, WDAS; Dayarathne, HKCO; De Silva, JGDS [Conference-Abstract]

Wind power is one of the largest sustainable alternative energy source used in the world for power generation. Though wind resource rich areas are available widely in Sri Lanka, excessive development of wind power plants ...
Synthesizing fuzzy linguistic vocal responses by adapting perception of robot based on visual attention

Muthugala, MAVJ; Jayasekara, AGBP [Conference-Abstract]

This paper proposes a method for adapting robot’s perception to produce fuzzy vocal responses about the size of an object based on the visual attention of the robot. In a humanhuman interaction, the humans may use vocal ...
