    • A comparison of circular object detection using Hough transform and chord intersection 

      Mohamed Rizon, Mohamed Juhari; Haniza, Yazid; Puteh, Saad (Institute of Eelectrical and Electronics Engineering (IEEE), 2007-07)
      In this paper, the circular Hough transform (CHT) and the chord intersection have been used to find the circular object in the feature extraction process. The chord intersection technique does not require any gradient ...

    • Fast background subtraction for real time monitoring 

      Sundaraj, Kenneth; Retnasamy, V. (International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)
      We present an implementation for fast detection of moving objects in real time monitoring applications. We apply a common technique known as background subtraction for this purpose. Background subtraction can be defined ...

    • Iris recognition system by using support vector machines 

      Ali, H.; Salami, M.J.E; Wahyudi (Institute of Electrical and Electronics Engineering (IEEE), 2008)
      In recent years, with the increasing demands of security in our networked society, biometric systems for user verification are becoming more popular. Iris recognition system is a new technology for user verification. In ...

    • On stereo processing procedure applied towards blind navigation aid - SVETA 

      Balakrishnan, G.; Sainarayanan, G.; Nagarajan, Ramachandran; Sazali, Yaacob, Prof. Dr. (Institute of Electrical and Electronics Engineering (IEEE), 2005)
      This paper presents a portable traveling support system using stereo image processing for the visually impaired people's navigation. This system named as SVETA consists of a helmet molded with stereo cameras in the front, ...

    • Optical tomography system using microprocessor and ethernet 

      Ruzairi, Abdul Rahim; Goh, Chiew Loon; Chan, Kok San; Pang, Jon Fea; Leong, Lai Chan; Mohd Hafiz, Fazalul Rahiman (Emerald Group Publishing Limited, 2010-01-01)
      Purpose: Owing to the high cost of data acquisition (DAQ) card in the market, the purpose of this paper is to develop a high speed, low-cost microprocessor and ethernet controller-based DAQ in optical tomography system. ...

    • Personalized face emotion classification using optimized data of three features 

      Muthukaruppan, Karthigayan; Ramachandran, Nagarajan; Mohd Rizon, Mohamed Juhari; Sazali, Yaacob (Institute of Electrical and Electronics Engineering (IEEE), 2007)
      In this paper, lip and eye features are applied to classify the human emotion through a set of irregular and regular ellipse fitting equations using Genetic algorithm (GA). South East Asian face is considered in this study. ...

    • Tilt detection of connectors using phase shifting 

      Retnasamy, V.; Mani Maran, Ratnam; Sundaraj, Kenneth; Zaliman, Sauli (International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)
      AVI's are playing important roles in quality inspection in the electronic industry. Most existing AVIs are single overhead camera and are incapable detecting 3D defects. This work presents solving the shortcoming stated ...

    • Ultrasonic tomography - image reconstruction algorithms
