Imagers based on focal plane arrays (FPA) risk introducing in-band and out-of-band spurious response, or aliasing, due to undersampling. This can make high-level discrimination tasks such as recognition and identification much more difficult. To overcome this problem, three-chip color charge coupled device (CCD) cameras typically offset one CCD by 1/2 pixel with respect to the other two. Analogously, monochrome imagers including infrared can use microscan (or dither) to reduce aliasing. This...
WaveLab is a collection of Matlab functions that have been used by the authors and collaborators to implement a variety of algorithms related to wavelet analysis. A partial list of the techniques made available: * orthogonal and biorthogonal wavelet transforms, * translation-invariant wavelets, * interpolating wavelet transforms, * cosine packets, * wavelet packets, * matching pursuit, and a lot more; Here is a more detailed introduction.
Intel® Threading Building Blocks (TBB) offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you take advantage of multi-core processor performance without having to be a threading expert. Threading Building Blocks is not just a threads-replacement library. It represents a higher-level, task-based parallelism that abstracts platform details and threading mechanisms for scalability and performance.
New in blender is a physically based volume material type, intended for rendering participating media, such as smoke, clouds, fog, and other volumetric effects. All procedural textures are supported as data sources, as well as two new textures for rendering voxels (such as our the smoke simulator) and point clouds.
Spectral rendering The core of Luxrender is fully spectral. Unlike traditional rendering software, which only operates on distinct colors (such as red, green and blue), Luxrender uses individual wavelengths. This allows LuxRender to correctly deal with wavelength dependent effects, such as dispersion, or accurately capture the color of incandescent lights. It also makes the rendered images look more natural.
These images are hemispherical panoramas, taken as addition to my Virtualvienna Project. You can find there some of the panoramas as full panorama in a bigger size than here.
POLarization and Directionality of the Earth's Reflectances The French space agency, CNES, has developed the POLDER instrument, which flew on ADEOS (ADvanced Earth Observation Satellite), developed by the Japanese space agency, JAXA. This was the first French/Japanese cooperative project in the area of Earth observation. A second, identical instrument flew on ADEOS-2, successor to ADEOS, until October 2003.
This presentation was given as a scheduled talk at PyCon UK 2007. The material presented covered the following subjects: * Generating code from user interface descriptions with pyuic4 * Connecting signals and slots using auto-connection * Creating custom widgets with PyQt4 for use in Qt Designer
Washington Post reporters Dana Priest and William M. Arkin spent two years investigating the government's response to 9/11. Top Secret America explores what they found.
Tux4Kids develops high-quality software for kids, with the goal of combining fun and learning into an irresistable package. Our software is free: you can download it for use at home or onto hundreds of computers in a school. We support all major platforms, including Windows, Macintosh, and Linux/Unix. Our programs are used by people around the globe, and they have been translated into dozens of different languages. As open-source software, these programs can be freely extended or customized, and they are supported by active communities of volunteer developers.
From the user's perspective, MDP is a collection of supervised and unsupervised learning algorithms and other data processing units that can be combined into data processing sequences and more complex feed-forward network architectures.
