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 ...
Gradient based adaptive thresholding
(Elsevier Ltd., 2013)
For images with poor and non-uniform illumination, adaptive thresholding is required to separate the objects of interest from the background. In this paper a new approach to create an adaptive threshold surface is proposed ...
Edge sharpening for diabetic retinopathy detection
(IEEE Conference Publications, 2010-06)
People with diabetes may face eye problem as a complication of diabetes. These eye problems can cause vision loss and even blindness. There are several lesions that appear such microaneurysms, hemorrhages, cotton wool spots ...
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 ...
Preparation of SiC-based composites by cold isostatic press
(American Institute of Physics, 2010-03-11)
The effect of polyvinyl alcohol binder on green strength of isostatic pressed silicon carbide was studied. A lab-top spray dryer was used to coat mixed powders with the binder. The resultant powders were pressed in a steel ...
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 ...
Discontinuities detection in welded joints based on inverse surface thresholding
(Elsevier Ltd., 2011)
Automated detection of welding defects in radiographic images becomes nontrivial when uneven illumination, contrast and noise are present. In this paper, a new approach using surface thresholding method is proposed to ...
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 ...
