Q2. What future works have the authors mentioned in the paper "A survey of graph theoretical approaches to image segmentation" ?
The use of graph as a representation of the image provides us an effective way to study the problem of image segmentation. The close relationship between them is not by accident and can be easily understood in two folds. Particularly, in recent years the emergence of many new algorithms proves that this category of techniques is still a promising research direction in the image segmentation community. Further study can refer to versatile graph based algorithms for a wide range of practical applications.
