Journal ArticleDOI
Retinal vessel enhancement based on multi-scale top-hat transformation and histogram fitting stretching
TL;DR: Results on the DRIVE and STARE databases show that the proposed method improves the contrast and enhances the details of the retinal vessels effectively.
Journal ArticleDOI
Retinal Fundus Image Enhancement Using the Normalized Convolution and Noise Removing
TL;DR: The results show that the proposed retinal fundus image enhancement method can directly enhance color images prominently and is different from some other fundu image enhancement methods.
Journal ArticleDOI
Automatic segmentation for cell images based on bottleneck detection and ellipse fitting
TL;DR: Experimental results show that the proposed method can effectively segment overlapping cells with high accuracy and less time, which is superior to many existing methods, and outperforms most of the existing algorithms with higher accuracy.
Journal ArticleDOI
A New Approach to Segment Both Main and Peripheral Retinal Vessels Based on Gray-Voting and Gaussian Mixture Model
TL;DR: The sensitivities of this approach were much higher than those of the other existing methods, with comparable specificities; these results thus demonstrated that this approach was sensitive to detection of small vessels.
Journal ArticleDOI
Altered Spontaneous Brain Activity of Children with Unilateral Amblyopia: A Resting State fMRI Study.
TL;DR: Unilateral amblyopia may reduce local brain activity and FC in the dorsal and ventral visual pathways and affect the top-down attentional control and alter FC between brain functional networks.
