Python implementation of distortion correction methods for X-ray tomography

Discorpy is a Python package implementing distortion-correction methods published in Optics Express by N.T Vo et al. It is useful for calibrating an imaging system with sub-pixel accuracy. The techniques require a single image of a calibration target. Discorpy was developed for calibrating lens-coupled detectors of tomography systems but it also can be used for commercial cameras. Since version 1.4, correction of perspective distortion was added to the package.
