Image distortion correction
Often by conducting the recording objects in the image received with the help of the digital camera are distorted. They can be pincushion and of barrel type. Such defects of the image can be caused by the difference of its scale in the center and around the edges. If original objects per se do not have a proper form, the distortion is not so clear, but when objects at the photo have vertical and horizontal lines, this distortion effect is noticeable and should be eliminated.
