Finding importance areas from images has been an important topic in graphics, multimedia and vision. In this paper, we present a supervised learning approach. We first collect a training set of color images and the labeled importance maps. Then we apply supervised learning to predict the importance maps as a function of the image. Our model uses a grid-shaped conditional random field that incor...

The shortest paths problem on weighted directed graphs is one of the basic network optimization problems. Its importance is mainly due to its applications in various areas, such as communication and transportation. Given a source node s in a weighted directed graph G, with n nodes and m arcs, the single-source shortest path problem (SSSP, for short) from s is the problem of finding the minimum ...
