A utility to produce MTF (modulation transfer function, a measure of edge acuity) maps of images. The program will automatically detect dark rectangular objects on light backgrounds, and extract MTF values on all edges. Can help to tune SLR autofocus. See http://mtfmapper.blogspot.com for more usage examples.

NOTE: We are moving this project to GitHub! Digital photographs are not ideal. Of course, the better is your camera, the better the results will be, but in any case if you look carefully at shots taken even by the most expensive cameras equipped with the most expensive lenses you will see various artifacts. It is very hard to make ideal cameras, because there are a lot of factors that affect the final image quality, and at some point camera and lens designers have to trade one factor...

HVVR (Hierarchical Visibility for Virtual Reality) is an optimized software raycaster. It implements a hybrid CPU/GPU raycaster, suited for real-time rendering of effects such as lens distortion. By default, raycaster.vcxproj is configured to build all .cu files to the compute_61,sm_61 target. If your GPU needs a different code-gen target, you can change this in the raycaster project properties. Some installations of the CUDA SDK and Visual Studio integration appear to have broken build...

dlRaw manipulates raw images from digital cameras. Besides dcraw functions, it does exposure correction, curve application in RGB/CIELAB space and USM or Refocus sharpening. Includes lensfun for lens corrections and greycstoration for noise reduction

The application was designed for the real time contactless photoplethysmography of the human face by means of an ordinary webcam in ambient light environment System requirements: - AMD or Intel CPU with 2 cores and 2.6 GHz clock speed (or higher); - 512 Mb of RAM (or higher); - OS Microsoft Windows 10/8/7/XP, booth 32 and 64 bit versions; - A RGB webcam (Logitech B910 is the best choice).

Photoropter is a lens correction library and calibration application. Comparable in purpose to existing projects like PTLens and LensFun, this is a new effort, using modern C++ libraries like Boost and STL and employing clean, object-oriented design.

Quick and dirty hardware random number generator that converts a digitized chaotic source (such as a lens capped web camera) into the random numbers. May or may not be cryptographically strong. 0.5-5MBiPS. Requires DirectShow enabled webcam. Win32. CLI.

met_3deLensDistort: A 3D Equalizer Lens Warp Plug-in for Shake

A tool designed to allow users to perform keystoning of a projection unit when the target surface may be an odd shape or at an angle that is not parallel to the projection lens.

The main purpose of this (once educational) software is to generate and visualize terrain using fractal algorithms. It uses OpenGL and includes many advanced features like: multi texturing, shadows, clouds, fog, LOD, lens flares, shaders ...
