This paper aims to be an outlet for speeding up workflow of orthopedics surgery and be helpful for surgeons to simply coordinate transformations between several imaging displays. Based on epipolar geometry and simple feature landmarks, a 3-D superimposed imaging approach is developed via the construction of the camera-projector system. The superimposed approach is to rectify the perspective, X-ray...
In this paper, a system is designed for improving the quality of novel view synthesis. To make the virtual view synthesis look better, the basic idea is to perform model refinement with important camera information of the novel view. In this system, we first use the reconstructed visual hull from shape from silhouette and then refine this 3D model based on the view dependency. The 3D points of the...
This paper presents a novel encoding method for scene change detection and appearance-based topological localization framework. The relation computation over convex hull points is used to compare the similarity between the scenes. It relies on the relative ordering of the feature strength, not directly on the feature vectors. We first deal with multiple convex hulls over the detected features and...
In this paper we propose a 3D reconstruction algorithm by combining shape from silhouette with stereo. Visual hull of the object is first derived from multi-view silhouette images. Pairwise stereo matching for shape refinement is then accomplished using the best viewable images. Based on the reduced correspondence searching range constrained by contact points and bounding edges, significant improvement...
Active camouflage is a technique for occluding objects disappear from the observer. Current implementations make assumptions on the viewpoints of both the observer and the camouflaged target. In this work, we present a framework of view-dependent planar scene camouflage. The cameras representing the observer and the occluding object are placed in general positions. The images captured by the object...
