Create a DLL for the removal of the lens distortion (pincushion, barrel, mustache). Definition of lens distortion from the input data from scanned calibration grid. Exists many open open projects as LensFun, Photoropter, and more (in C++, Matlab). You can only use and modify the available resources and convert them into dll (32bit and 64bit).
1) fast efficient library dll (input image around 5MP)
2) without losing the quality of the input image (it is more important to image quality than the speed of processing)
3) tool for determining lens distortion (calculate lens distortion based on insert scanned calibration grid)
4) sample code for use in [url removed, login to view]
