The purpose of this paper is to research the image semantic auto-annotation method, which proposes an image semantic annotation method adopted ontology description and the image regional objects reasoning. First, the image semantic regional description model was build, and then the similar features of the region to achieve the similar semantics were annotated. Second, the algorithm focuses on the...
Road tracking is a promising technique to increase the efficiency of road mapping. In this paper, a new semi-automatic road tracker, parallel angular texture signature (PATS) is presented. The tracker is object-oriented in some sense, because it makes best use of the texture signature of road primitives on high-resolution remotely sensed imagery. Our tracker uses parabola to model the road trajectory...
This paper presents a new image segmentation algorithm based on edge-preserving watershed for the auto-segmentation of SAR sea ice images, which can solve the conflict between simplifying image for watershed based on H-minima and preserving the object edge. Iterative bilateral filtering is first used to preprocess the image and it can preserve the edge well. Watershed segmentation based on H-minima...
Road tracking is a promising technique to increase the efficiency of road mapping. In this paper, a new road tracker, angular texture signature, is proposed based on the knowledge of the roads on high resolution imagery. The tracker uses parabola to model the road trajectory and predict the position of next road centreline point. It employs angular texture signature to get the moving direction of...
