Applied maths studies

Paper reports, processed data, and consulting : applied maths study made by NEXYAD for you, on the basis of your task book plus (usually) a set of data : : Artificial vision, detection, pattern recognition, image processing, signal processing and understanding, virtual sensors, data analysis, statistics, modeling, ...

Software

The Ultimate pattern recognition application generator : RecogNex^TM
RecogNex^TM is a professional software that AUTOMATICALLY generates effective pattern recognition applications.
Inputs of this tool are rough data and preprocessed data (using YOUR descriptors to preprocess data). From this external input, RecogNex automatically computes new preprocessings (neural networks based automatic information extraction), and edits statistics about the discrimination power of rough data, of your preprocessed data, and of data preprocessed by the automatic RecogNex^TM preprocessing module.
Those input data are used together by a fuzzy sets-based pattern recognition system that is also automatically calibrated (using advanced statistics + stochastic learning). Several pattern recognition systems are automatically built (with all inputs, the minimum possible number of inputs, ...), and they are automatically tested and compared. In the end, RecogNex^TM generates the C code of the best pattern recognition application.

All you need in order to apply RecogNex^TM is a data base with your set of quantitative and qualitative variables among individuals, plus a qualitative variable giving the class number. You can also use other qualitative variables that should describe the context (ex : 1 = it was raining, 2 = the weather was fine, ...), so the learning and test data bases builder (this is also automatic) will take into account quotas and statistical constraints for representative sampling using this context description : your data bases will be as most representative as possible => robustness is optimized.

Software on request

Special software made for you (structured upon our applied maths algorithms library). The developed software is entirely specialized in solving efficiently a given recurrent project : you can run it on your own data. Vocabulary of the user interface uses professional words of YOUR job : no need to hire a mathematician to use the software

Products : wiper systems tester (rubbers, rain sensors, windshield, intelligent wiper triggering, ...)

These systems include sensors, hardware, software - applied-maths models of human vision behaviour, mechanics, ...
We propose 3 integrated systems for the wiper systems tests and tuning :

RainNex^TM: RainNex is a programmable rain machine (with artificial rain very similar to natural rain : no need to wait for the rain anymore). With RainNex, it is possible to have exactly the same statistics of rain on the driver's vision area and on the rain sensor area (whatever the location of the rain sensor is).

VisiNex^TM : VisiNex lets you evaluate among time distance of visibility and visual quality score through the windscreen. Wiper is supposed to recover visibility : this recovery is "measured" (quantitative and absolute marks of visibility that allow the comparison/benchmarking of several wiper systems (including rain sensors, decision making software, quality of rubbers, ...

DropNex^TM : DropNex lets you count among time rain drops on a windscreen (size, statistics, ...). You can specify a rain machine (measure rains outdoor, and then provide statistics of rain as a target for a future rain machine). You can sharply tune your rain machine in order to reproduce interesting kinds of rain. You can analyse cases of "wiper failure" and know exactly which kind of rain occurs in such a case.

On-board algorithms for Advanced Driver Assistance Systems

NEXYAD developed 4 algorithms that are ready for integration into your on-board applications : we can sell the technology (licence for R&D use, licence for integration into your products, technology transfert, property transfert, ...).

Most of these algorithms are available in two versions : stand alone dll, or ".pck" components for the real time simulation and development environment RT-MAPS (from the French company Intempora).
Three algorithms are artificial vision ones :
- obstacle detection (from a single camera)
- road detection (from a single camera)
- visibility estimation (from a single camera)

Real time image binarization algorithm for smart cameras

NEXYAD developed a very fast binarization algorithm (very low computing and memory resources requested) for large image sequences that leads to 1-bit per pixel data flow and keeps the scene understandable for human eye. Perfect for real time remote monitoring applications and decision making from smart cameras.
