Spatial Transform and Lens Distortion Correction (STLDC) is designed to contain a suite of functions which perform spatial transformation on images as well as modules to calibrate and correct the lens/fish-eye lens distortion in camera. It uses various primitives from the ADI Blackfin Image Processing Toolbox Library and provides solutions to various applications like camera parameter calibration, correction of images for lens distortion, affine transform etc. The above functions require non-sequential picking of data for each pixel of the image and hence there is usage of memory DMA (MDMA) infrastructure within the core functions.
