What are three main differences between Marx and Lenin?
1) Marx was an armchair theorist, while Lenin was a practitioner and in the end took power in Russia. 2) Marx developed his theory watching 19th-century industrial societies in Western Europe, while Lenin adapted Marxism to the realities of 20th-century Imperial Russia, where peasants constituted 4/5th of the population. 3) Marx was a lousy party […]
Main Question of Data Analysis
Can we be confident in the patterns that we are seeing in the data or what we are observing is just noise? The answer is not 42. Slava23+ years’ programming and theoretical experience in the computer science fields such as video compression, media streaming and artificial intelligence (co-author of several papers and patents). the author […]
Turing HEVC Codec

Grain Noise Detection Algorithm
Introduction Film grain is a particular random noise on photographic film due to the presence of small particles of a metallic silver, or dye clouds: Digital photography in virtue does not exhibit film grain. However a film grain overlay is sometimes added as a special effect onto digital content. There exist a number of […]
The Size of Tip in Restaurant
Famous social psychologist Bibb Latante visiting hundreds of Parisian restaurants empirically inferred the following formula, how the size of the tip depends on a number of people sitting at table: p = k Nt where t<1, N is the number of guests at table p – tip k – coefficient (= quality of service) […]
WebP Still Image Format
WebP Still Image Format was released by Google in September 2010. WebP is based on VP8 intra coding. WebP supports both lossless and lossy compression. It is reported to offer 39.8% more byte-size efficiency than JPEG for the same quality. For more results of WebP comparison with other still image codecs (JPEG, JPEG2000, JPEG XR) […]

VQMT – Video Quality Metric Tool
There is a free VQMT tool, slightly “ancient” from 2013, you can find the link to windows binaries at http://mmspg.epfl.ch/vqmt or take my binaries . VQMT computes such video quality metrics as PSNR, SSIM, MSSSIM (Multi-Scale SSIM), VIFP (Visual Information Fidelity), PSNRHVS (Peak Signal-to-Noise Ratio taking into account Contrast Sensitivity Function). Notice that PSNR is […]
