The graphics processing unit (GPU) has become part of our everyday life through desktop computers and portable devices (tablets, mobile phones, etc.). Because of the dedicated hardware visualization has been significantly accelerated and today’s software uses only the GPU for rasterization. Besides the graphical devices, the central processing unit (CPU) has also made remarkable progress. […]

Gaussian mixture models (GMMs) are often used in various data processing and classification tasks to model a continuous probability density in a multi-dimensional space. In cases, where the dimension of the feature space is relatively high (e.g. in the automatic speech recognition (ASR)), GMM with a higher number of Gaussians with diagonal covariances (DC) instead […]

The market of computer graphics is dominated by GPU based technologies. However today’s fast central processing units (CPU) based on modern architectural design offer new opportunities in the field of classical software rendering. Because the technological development of the GPU architecture almost reached the limits in the field of the programming model, the CPU-based solutions […]

With the rise of general purpose computing on graphics processing units (GPGPU), the influence from consumer markets can now be seen across the spectrum of computer architectures. In fact, many of the high-ranking Top500 HPC systems now include these accelerators. Traditionally, GPUs have connected to the CPU via the PCIe bus, which has proved to […]

We developed a very fast reprojection technique to generate stereoscopic images from a 2D image with depth information. The technique is gather-based and therefore very fast on current graphics hardware. The depth information is sampled at a specific offset which provides the depth to reproject from the left or right camera to the center camera. […]
