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 ...
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 ...
