http://www.sourceafis.org/blog/fingerprint-recognition-sdk-review
Fingerprint Recognition SDK Review. September 15, 2012. This is a concise review of biometric qualities of the opensource project Fingerprint recognition SDK. Documented roughly in a presentation by Oleg Ostap. Global contrast normalization – Histogram, clip some top/bottom pixels, normalize. Mask – Limit on block darkness or limit on gradient. Gradient is computed from oddly smoothed image. Gradient limit is relative to average gradient in image. Median smoothing – Median is computed within circle...

Donate Fingerprints to SourceAFIS | SourceAFIS
http://www.sourceafis.org/blog/donate-fingerprints
Donate Fingerprints to SourceAFIS. September 15, 2012. Quality of matching can vary from device to device, because each fingerprint reader has unique characteristics that require different matching parameters. I would like to make SourceAFIS work smoothly with every single fingerprint reader available on the market. There’s already quite a long list of tested fingerprint readers. Once you have a directory full of fingerprints, just zip it and send it to me. Via free account on mailbigfile.com.

C++ tutorial - CRC-32C (Castagnoli) for C++ and .NET
https://crc32c.angeloflogic.com/tutorial-cpp
CRC-32C (Castagnoli) for C and .NET. The library, your first step is to include the header:. After that, you will get access to the following function:. You can call the function like this:. Uint32 t crc = crc32c append(0, input, 10000);. As the comments in above declaration suggest, you can compute crc from multiple chained buffers:. Uint32 t intermediate = crc32c append(0, input, 3000); uint32 t crc = crc32c append(intermediate, input 3000, 7000);. CRC-32C for C and .NET. 20 GB/s in hardware.

There have been many efforts to port Snappy to Windows. Snappy for Windows. Aims to be the most complete, the most up to date, and the most stable one. I will briefly mention existing ports and their relative strengths and weaknesses. Snappy for .NET. Developed mostly to compare performance with LZ4 compressor that is a close relative of Snappy. It includes native DLL build as well as .NET wrapper. I have copied bit counting optimization from this port. Snappy for .NET on CodePlex. This is another pure &...
