Object detection using circular hough transform
(Science Publications, 2005)In this study we propose a new system to detect the object from an input image. The proposed system first uses the separability filter proposed by Fukui and Yamaguchi (Trans. IEICE Japan J80-D-II. 8, 2170-2177, 1997) to ... -

Object localization using stereo sensors for adept SCARA robot
(Institute of Electrical and Electronics Engineers (IEEE), 2006)In this paper we present a stereo vision system for segmentation of partially occluded objects and computation of object grasping point in bin picking environments. The stereo vision system was interfaced with an Adept ... -
Objective analysis of vision impairments using single trial VEPs
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)Visually evoked potential (VEP) is an electrical signal generated by the brain (Occipital Cortex) in response to a visual stimuli. These VEP are recorded non-invasively by placing the surface electrodes at the scalp, and ... -
Objective evaluation of speech dysfluencies using wavelet packet transform with sample entropy
(Elsevier Inc, 2013-05)Dysfluency and stuttering are a break or interruption of normal speech such as repetition, prolongation, interjection of syllables, sounds, words or phrases and involuntary silent pauses or blocks in communication. Stuttering ... -
Objective investigation of vision impairments using single trial pattern reversal visually evoked potentials
(Elsevier Ltd., 2013-07)Visually evoked potentials (VEPs) originate from the occipital cortex and have long been used as a reliable indicator for vision impairments by ophthalmologists. Any abnormalities in the visual pathways of a person can be ... -
Omni-Directional Mobile Robot with mecanum wheel
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-14)In this paper, we review researches on omni-directional mobile robot design which Mecanum wheel as component in mobile robot propulsion. Omni-directional mobile robot has vast advantages over conventional design likes ... -
On stereo processing procedure applied towards blind navigation aid - SVETA
(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 Face-Contour Analysis - O. F-C. A
(Malaysian Invention and Design Society (MINDS), 2010-05-14)Security has become our greatest safety concern in the 21st century due to ever increasing crime rates and severity. This has prompted identification of persons with crime history, however, with the most affordable price ... -
Optimization of circular side door beam for crashworthiness analysis
(Indonesian Society for Knowledge and Human Development (INSIGHT), 2012)Structural optimization related to crashworthiness and energy absorption capability is particularly importance to the automotive industry. The optimization involves highly nonlinear computational analysis and design with ... -
Optimum part deposition orientation and adaptive slicing in fused deposition modeling
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-14)Part deposition time and surface finish are two important concerns in rapid prototyping (RP). These two items contradict with each other. Commonly, a concession is made between the two aspects pertaining to model building ... -
Overview of automatic stuttering recognition system
(Universiti Malaysia Perlis, 2009-10-11)Stuttering is a speech disorder. The flow of speech is disrupted by involuntary repetitions and prolongation of sounds, syllables, words or phrases, and involuntary silent pauses or blocks in communication. Stuttering is ... -
Pathological infant cry analysis using wavelet packet transform and probabilistic neural network
(Elsevier Ltd., 2011-11)A new approach has been presented based on the wavelet packet transform and probabilistic neural network (PNN) for the analysis of infant cry signals. Feature extraction and development of classification algorithms play ... -
Patient monitoring in ICU under unstructured lighting condition
(IEEE Conference Publications, 2010-10)In this paper, fuzzy classifier is explained and reviewed for detecting facial changes of patient in a hospital in Intensive Care Unit (ICU). The facial changes are most widely represented by eyes and mouth movements. The ... -
Patients tremble analysis under different camera placement in critical care
(Science Academy, 2011-03)This paper presents an integrated system for detecting facial changes of patient in a hospital in Intensive Care Unit (ICU). In this research we have considered the facial changes most widely represented by eyes and mouth ... -
Performance comparison of daubechies wavelet family in Infant cry classification
(IEEE Conference Publications, 2012)Infant cry is a non-stationary, loud, high-pitched signal made by infants in response to certain situations. This acoustic signal can be used to identify physical or psychology status of infant. The aim of this work is to ... -
