This paper presents a model for correcting the effects of barrel and pincushion lens distortion that preserves the scale of the captured image. This is significant as the model is able to correct for a practical range of the aforementioned types of lens distortion while maintaining the scale helps minimize the loss of the corrected image’s resolution. The functional inverse of the model is deri...

Image registration is the process of approximate matching source image to target so that they resemble each other. In this study, two-dimensional presented using rigid group. This group a finite dimensional (four-dimensional in case) under composition. The dimensions are scaling, rotation, and translations along axes. paper, an algorithm for construction transformation discretized objective fun...
