Uniformly

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a... Platforms: Matlab

The task of this work is to extract a signal radiating from a specific direction in the presence of a jamming signal being transmitted at same frequency.There are four cases in the first case transmitter and jammer are in different directions and are at equal range from receiver but the jammer is...

fSGolayFilt is a fast polynomial smoothing filter for uniformly spaced signals. This implementation offers less flexibility than other versions found in the MATLAB Central (eg. from Jianwen Luo, YangQuan Chen or Vassili Pastushenko), but it is optimized for speed by using a C-Mex function for the...

Publimark is a command line tool to secretly embed text in an audio file. Like cryptography, Publimark project uses a pair of keys: the public one can be shared, whereas the private one must be kept secret. Anybody can send a steganographic message, but only the private key owner will be able... Platforms: *nix

LibTMCG is a general purpose C++ library for creating secure electronic card games. The most remarkable feature is the absence of a trusted third party (TTP), i.e. neither a central game server nor trusted hardware components are necessary. To emphasize this point again: With the present... Platforms: *nix

UV Outliner is a small and powerful single-pane outliner. It is intended for creating, organizing, and collecting information. With UV Outliner you can create plans, schedules, and to-do lists, collect and organize ideas, brainstorm, plan your trips, record meeting minutes, track expenses,... Platforms: Windows

Logic test. It is difficult enough. A test group of 2000 members gave on average 3.04 right answers (from 10 available). This test doesn measure intelligence quotient itself, as this quotient still is not uniformly defined. It shows you difficult logic problems instead and counts the number of... Platforms: Windows

Ever gotten the minute and hour hands confused? Wondered whether it was AM or PM? Found digital clocks a little too abstract?. The Disk Clock moves multiple disks in what would be the clock face. Each disk has it's own distinct appearance. There is only one hand. You know where you are - time... Platforms: Mac

SMOOTHN provides a fast, unsupervised and robust discretized spline smoother for data of any dimension.SMOOTHN(Y) automatically smoothes the uniformly-sampled array Y. Y can be any N-D noisy array (time series, images, 3D data,...).SMOOTHN can deal with missing (NaN) values (see screenshot, top... Platforms: Matlab

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector. It also works on any specified dimension of... Platforms: Matlab

SVMs are a bit tricky. In this case, we show a linear SVM and illustrate its behaviour on some 2D data. This should be great for getting to grips with maximising geometric margins, support vectors, and the optimisation involved in computing an optimal separating hyperplane.Data can be generated...
