This paper presents a novel disparity map refinement method and vision based surveillance framework for the task of detecting objects of interest in dynamic outdoor environments from two stereo video sequences taken at different times and from different viewing angles by a mobile camera platform. The proposed framework includes several steps, the first of which computes disparity maps of the same...
Glassless 3D display requires multiple images taken from different viewpoints to show a scene. Thus, generating such a large number of viewpoint images effectively is emerging as a key technique in 3D video technology. Image-based view synthesis is a technique of generating required virtual viewpoint images using a limited number of views and depth maps. In this paper, we propose an algorithm to compute...
Underwater, natural illumination typically varies strongly temporally and spatially. The reason is that waves on the water surface refract light into the water in a spatiotemporally varying manner. The resulting underwater illumination field is known as underwater caustics or flicker. In past studies, flicker has often been considered to be an undesired effect, which degrades the quality of images...
Depth maps are playing an important role in the multi-view system. For multi-view, depth maps can be used not only for image-based rendering (IBR), but also for multi-view stereo reconstruction by merging depth maps into 3D models. In this paper, we propose a novel approach to recover depth maps for multi-view. The most contribution of our work is the combination of a robust photo-consistency metric...
This paper describes a method to correct the distortions in the images captured by a stereo video camera rig. We developed a code which can be implemented both on CPUs and GPUs which are used respectively to process still images or videos. The processing scheme is centered on the pre-calculation of a deformation texture, based on the physical properties of the camera setup (intrinsic parameters)....
Recently, many researchers are actively studying on the reconstruction of 3-dimensional structures from the 2-dimensional images acquired from a stereo camera. However, the disparity map calculated from the existing methods does not always provide accurate depth information by the false matching and occluded areas. In this paper, by simultaneously applying the feature-based methods [1] and region-based...
