By: S. Nebiker; M. Christen

Description: Institute of Geomatics Engineering, FHNW University of Applied Sciences and Arts Northwestern Switzerland, Muttenz, Switzerland. Rendering large city models with high polygon count and a vast amount of textures at interactive frame rates is a rather difficult to impossible task as it highly depends on the client hardware, which is often insufficient, even if out-of-core rendering techniques and level of detail approaches are used. Rendering complex city mo...

Description: Dept. of Natural Resources and Environmental Engineering, University of Vigo, Maxwell s/n, 36310, Vigo, Spain. Rubble mound breakwaters are coastal defense structures that protect harbors and beaches from the impacts of both littoral drift and storm waves. They occasionally break, leading to catastrophic damage to surrounding human populations and resulting in huge economic and environmental losses. Ensuring their stability is considered to be of vital imp...

By: M. V. Joshi; R. C. Patel

Description: Dhirubhai Ambanin Institute of Information and Communication Technology (DAIICT), Gandhinagar, Gujarat State, India. Over the past decade hyper spectral (HS) image analysis has turned into one of the most powerful and growing technologies in the field of remote sensing. While HS images cover large area at fine spectral resolution, their spatial resolutions are often too coarse for the use in various applications. Hence improving their resolution has a high...

Object-level Segmentation of Rgbd Data : Volume Ii-3, Issue 1 (07/...

By: C. Brenner; H. Mayer; H. Jiang; H. Huang

Description: Institute of Applied Computer Science, Bundeswehr University Munich, Neubiberg, Germany. We propose a novel method to segment Microsoft™Kinect data of indoor scenes with the emphasis on freeform objects. We use the full 3D information for the scene parsing and the segmentation of potential objects instead of treating the depth values as an additional channel of the 2D image. The raw RGBD image is first converted to a 3D point cloud with color. We then grou...
