Capturing and creating models of human subjects is an ongoing effort in computergraphics. In this paper, we present a framework to capture, model, simplify, and stylize an human subject. We use a consumer 3D depth ca...

""This study proposes a framework to photorealistically synthesize virtual objects and virtualized real-world. We combine the offline rendering of virtual objects and the free-viewpoint image generation to take advantage of the higher quality of offline rendering without the computational cost of online computergraphics (CG) rendering; i.e., it incurs only the cost of the online computation for the free-viewpoint image generation. In addition, the generation of structured viewpoints (e.g., at every grid point) reduces the computational costs required to online process.""
In recent years, many approaches for real-time simulation of physical phenomena using particles have been proposed. Many of these use 3D grids for representing spatial distributions and employ a collision detection te...

We think that state-of-the-art techniques in computergraphics and geometry processing can be leveraged in training and entertainment to make the topic of cultural heritage more accessible to a wider audience. In a cooperation with the "Antikensammlung" in Erlangen we produced five unique applications - all based around emperor Augustus - to visualize different scientific aspects for a big event targeted towards the general public. The applied methods include blending, geometric fitting, animation transfer and visualization techniques. Besides being entertaining, some of the presented applications are the foundation for more substantial research. (For our results video please visit http://***/uploads/video/***).

Most imageprocessing algorithms are inherently parallel, so multithreading processors are suitable in such applications. In huge image databases, imageprocessing takes very long time for run on a single core processor because of single thread execution of algorithms. GPU is more common in most imageprocessing applications due to multithread execution of algorithms, programmability and low cost. In this paper we show how to implement the MPRG-7 Edge Histogram Descriptor in parallel using CUDA programming model on a GPU. The Edge Histogram Descriptor describes the distribution of various types of edges with a histogram that can be a tool for image matching. This feature is applied to search images from a database which are similar to a query image. We evaluated the retrieval of the proposed technique using recall, precision, and average precision measures. Experimental results showed that parallel implementation led to an average speed up of 14.74xover the serial implementation. The average precision and the average recall of presented method are 67.02% and 55.00% respectively.
There are many scenarios in which user interaction is essential for effective image segmentation. In this paper, we present a new interactive segmentation method based on the image Foresting Transform (IFT). The metho...
