Saliency detection is an important problem in many computer vision applications. As a kind of popular method, graph based manifold ranking (GMR) has been successfully used in saliency detection problem. In traditional GMR saliency detection, it involves two main stages, i.e., ranking with background queries and ranking with foreground queries. However, in GMR method, these two stages are conducted...
We present an improved algorithm to RRT∗ in this paper. Our algorithm tries to increase the efficiency by replacing the Initialtree() of RRT∗ with a RRT tree only contains one solution to speed up finding a feasible solution, and then applying a RRT∗_S algorithm to optimize the current solution. This RRT∗_S is similar with RRT∗ in principle, but it does not insert extra nodes into the current tree...
