Automated thresholding in radiographic image for welded joints
(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 ...
Automated identification of exudates and optic disc based on inverse surface thresholding
(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 ...
Background correction using average filtering and gradient based thresholding
(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 ...
Exudates segmentation using inverse surface adaptive thresholding
(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. The strategy involves the applications of fuzzy c-means clustering, edge detection, otsu ...
Detection of Pulmonary Nodule using Shape-Based Feature Descriptor and Neural Network
(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 ...
Image quality assessment (IQA) using high-frequency and image variance (HFIV) for colour image
(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 ...
Illumination and contrast correction strategy using bilateral filtering and binarization comparison
(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 ...
