With the development of Internet, online social networks and websites generate a large amount of data. At the same time, several distributed systems, represented by Hadoop, has been proposed to handle mass data. These systems provide both efficient and convenient way to construct different kinds of algorithms. Community detection, a traditional research area, is now facing the challenge of Big Data...
This paper proposes an algorithm to measure the width of retinal vessels in fundus photographs using graph-based algorithm to segment both vessel edges simultaneously. First, the simultaneous two-boundary segmentation problem is modeled as a two-slice, 3-D surface segmentation problem, which is further converted into the problem of computing a minimum closed set in a node-weighted graph. An initial...
