Image saliency detection has attracted much attention in recent years, while several challenging problems are still unsolved, such as inaccurate saliency detection in complex scenes and suppressing salient objects near image borders. In this paper, a novel algorithm is proposed to solve these problems. Firstly, we collect background seeds from image borders by boundary information and construct a...
As some of the valuable satellites can maintain working after on-orbit servicing, it's meaningful to study on the autonomous rendezvous. Most of these satellites are non-cooperative, more specifically, they have no target location markers or rendezvous sensors. This paper extracts the edge of the adapter ring as natures for recognition, measurement or even mechanical docking. A practical detection...
Most visual based obstacle detection methods usually detect obstacles on the whole image, which are influenced by complex background and various illuminations. This paper proposes a novel and simple obstacle detection method DLP based on analyzing Distortion of Laser Pattern. To reduce computation, a laser pattern with two cross lines is used to project onto the front ground. Firstly, a segmentation...
