Read e-book online Nonuniform Sampling: Theory and Practice (Information PDF

By Farokh Marvasti

Our knowing of nature is frequently via nonuniform observations in house or time. In area, one typically observes the $64000 positive factors of an item, resembling edges. the fewer very important positive factors are interpolated. historical past is a suite of significant occasions which are nonuniformly spaced in time. Historians infer among occasions (interpolation) and politicians and inventory marketplace analysts forecast the long run from earlier and current occasions (extrapolation). The 20 chapters of Nonuniform Sampling: conception and Practice include contributions through major researchers in nonuniform and Shannon sampling, 0 crossing, and interpolation thought. Its sensible functions comprise NMR, seismology, speech and snapshot coding, modulation and coding, optimum content material, array processing, and electronic clear out layout. It has an educational outlook for practicing engineers and complicated scholars in technological know-how, engineering, and arithmetic. it's also an invaluable reference for scientists and engineers operating within the components of scientific imaging, geophysics, astronomy, biomedical engineering, special effects, electronic filter out layout, speech and video processing, and phased array radar.

Download e-book for kindle: Real-Time Heterogeneous Video Transcoding for Low-Power by Tarek Elarabi,Ahmed Abdelgawad,Magdy Bayoumi

By Tarek Elarabi,Ahmed Abdelgawad,Magdy Bayoumi

This ebook introduces a unique transcoding set of rules for genuine time video functions, designed to beat inter-operability difficulties among MPEG-2 to H.264/AVC. the hot set of rules achieves 92.8% aid within the transcoding run time at a cost of a suitable top Signal-to-Noise Ratio (PSNR) degradation, allowing readers to exploit it for actual time video purposes. The set of rules defined is evaluated via simulation and experimental effects. moreover, the authors current a implementation of the hot set of rules utilizing box Programmable Gate Array (FPGA) and Application-specific average items (ASIC).

• Describes a singular transcoding set of rules for actual time video functions, designed to beat inter-operability difficulties among H.264/AVC to MPEG-2;
• Implements set of rules offered utilizing box Programmable Gate Array (FPGA) and Application-specific built-in Circuit (ASIC);
• Demonstrates the answer to genuine difficulties, with verification via simulation and experimental results.

Download e-book for kindle: Sparse Image and Signal Processing: Wavelets and Related by Jean-Luc Starck,Fionn Murtagh,Jalal Fadili

By Jean-Luc Starck,Fionn Murtagh,Jalal Fadili

This completely up-to-date re-creation provides cutting-edge sparse and multiscale picture and sign processing. It covers linear multiscale geometric transforms, reminiscent of wavelet, ridgelet, or curvelet transforms, and non-linear multiscale transforms in response to the median and mathematical morphology operators. besides an up to date description of required computation, it covers the newest leads to inverse challenge fixing and regularization, sparse sign decomposition, blind resource separation, in-painting, and compressed sensing. New chapters and sections disguise multiscale geometric transforms for third-dimensional information (data cubes), information at the sphere (geo-located data), dictionary studying, and nonnegative matrix factorization. The authors wed concept and perform in analyzing purposes in components reminiscent of astronomy, together with fresh effects from the eu area Agency's Herschel project, biology, fusion physics, chilly darkish topic simulation, clinical MRI, electronic media, and forensics. MATLAB® and IDL code, to be had on-line at www.SparseSignalRecipes.info, accompany those equipment and all applications.

Computer-Graphic Facial Reconstruction by John Clement PDF

By John Clement

This precise books appears to be like at a inexpensive, quickly and exact technique of facial reconstruction--from segmented, decomposed, or skeletal remains--using computer-graphic and computational means.

Computer-Graphic Facial Reconstruction is designed as a worthwhile source for these scientists designing new study tasks and protocols, in addition to a pragmatic guide of tools and strategies for medico-legal practitioners who truly determine the faceless sufferers of crime. It seems to be at various methods: synthetic intelligence utilizing neural networks, case-based reasoning, Baysian trust structures, besides a number of imaging tools: radiological, CT, MRI and using imaging devices.

The equipment defined during this publication supplement, or will even exchange, the less-reliable, extra conventional technique of securing identity by way of presumptive potential, i.e., reputation of garments, own results and clay reconstruction.

- Covers state of the art applied sciences within the context of ancient forensic reconstruction methods
- beneficial properties stellar authors from round the globe
- Bridges the components of special effects, animation, and forensic anthropology
