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 ...
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 ...
