    • 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 ...
