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 ...
Circular discontinuities detection in welded joints using Circular Hough Transform
(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. ...
Object detection using geometric invariant moment
(Science Publications, 2006)
Geometric moment invariant produces a set of feature vectors that are invariant under shifting, scaling and rotation. The technique is widely used to extract the global features for pattern recognition due to its discrimination ...
A comparison of circular object detection using Hough transform and chord intersection
(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 ...
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 ...
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 ...
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 ...
