    • 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 ...

    • Discontinuities detection in welded joints based on inverse surface thresholding 

      Haniza, Yazid, Dr.; Hamzah, Arof, Dr.; Hafizal, Yazid; Sahrim, Ahmad; Abdul Aziz, Mohamed; Fauzan, Ahmad (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 ...

    • 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. The strategy involves the applications of fuzzy c-means clustering, edge detection, otsu ...

    • Gradient based adaptive thresholding 

      Haniza, Yazid, Dr.; Hamzah, Arof, Dr. (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 ...
