Abstract:
1. A method for calculating a transformed image from a digital image and formatted information related to a geometric transformation, the formatted information being limited to defects of an appliance chain, the formatted information especially linked to distortions and/or to chromatic aberrations of the appliance chain, wherein the digital image is composed of digital pixels, the transformed image is composed of transformed pixels, and the transformed pixels are characterized by a transformed position and a transformed value, the method comprising: calculating the transformed image from an approximation of the geometric transformation; calculating values of the transformed pixels by employing a general algorithm that includes the formatted information containing parameters, the parameters making it possible to choose at least one mathematical function related to the geometric transformation, the at least one mathematical function making it possible to calculate the block of digital pixels and the digital position from the transformed position.
