Automated identification of exudates and optic disc based on inverse surface thresholding
Haniza, Yazid; Hamzah, Arof, Dr.; Hazlita, Mohd Isa, Dr. (Springer Science+Business Media, LLC., 2012)This paper presents a new approach to detect exudates and optic disc from color fundus images based on inverse surface thresholding. The strategy involves the applications of fuzzy c-means clustering, edge detection, otsu ... -
Automated thresholding in radiographic image for welded joints
Haniza, Yazid; Hamzah, Arof, Dr.; Hafizal, Yazid (Taylor & Francis, 2012)Automated detection of welding defects in radiographic images becomes non-trivial when uneven illumination, contrast and noise are present. In this paper, a new surface thresholding method is introduced to detect defects ... -
Background correction using average filtering and gradient based thresholding
Wan Azani, Mustafa; Haniza, Yazid (Universiti Teknikal Malaysia Melaka, 2016)Segmentation process on the image with illumination and contrast variation problem is a very challenging task. This problem can reduce the effectiveness of segmentation result. Therefore, the implementation of the proposed ... -
Circular discontinuities detection in welded joints using Circular Hough Transform
Hafizal, Yazid; Haniza, Yazid; Mohd Harun; Shukri Mohd; A. Aziz, Mohamed; Mohamed Rizon, Mohamed Juhari; Shaharudin, Sayutia (Elsevier B.V., 2007)Conventional radiography is one of the common non-destructive testing which employs manual image interpretation. The interpretation is very subjective and depends much on the inspector experience and working conditions. ... -
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 ... -
Detection of coconuts location using separability filter and Hough Transform
Haniza, Yazid; Mohamed Rizon, Mohamed Juhari; Sugisaka, Masanori; Puteh, Saad; Ali Yeon, Md Shakaff; Abdul Rahman, Mohd. Saad (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-14)In this paper, we develop a technique to determine coconuts location using separability filter and Hough transform method. Our research involves two sequential steps for solving the coconuts detection and recognition. The ... -
Detection of Pulmonary Nodule using Shape-Based Feature Descriptor and Neural Network
Nurfarhana Hazwani, Jusoh; Haniza, Yazid; Shafriza Nisha, Basah; Saufiah, Abdul Rahim (IOP Publishing, 2019)This research aims to detect the pulmonary nodule presented in lung Computed Tomography (CT) scan images. Generally, a Computer-Aided Diagnostic (CAD) system was designed and developed to aid the radiologists in medical ... -
Exudates segmentation using inverse surface adaptive thresholding
Haniza, Yazid; Hamzah, Arof, Dr.; Hazlita, Mohd Isa, Dr. (Elsevier B.V., 2012-07)This paper presents a new approach to detect exudates and optic disc from color fundus images based on inverse surface thresholding.

Illumination and contrast correction strategy using bilateral filtering and binarization comparison
Wan Azani, Mustafa; Haniza, Yazid (Universiti Teknikal Malaysia Melaka, 2016)Illumination normalization and contrast variation on images areone of themost challenging tasks in the imageprocessing field. Normally, the degrade contrast imagesarecaused by pose, occlusion, illumination,and ... -
Image quality assessment (IQA) using high-frequency and image variance (HFIV) for colour image
Li Chien, Tan; Haniza, Yazid; Yen Fook, Chong (IOP Publishing, 2019)Image quality is often lost during image acquisition, transmission, and compression. Therefore, image quality assessment (IQA) is crucial in image processing. Currently, image quality can be measured from the frequency ... -
