- W2847332821 abstract "Lens distortion is the result of radial variations in the lens magnification. It occurs with most low cost wide angle cameras and affects image quality. As a result, straight lines, particularly those in the periphery, appear curved. One dominant lens distortion correction approach is based on linear features within the image. This kind of correction method usually requires detecting edges or lines, and the Hough transform is a powerful tool to do so. In the Hough transform space, straight and curved lines yield patterns with different shapes. In this paper, a proof of concept is explored whereby lens distortion parameters are derived directly from analysing the shape of peaks within Hough transform space. Subsequently, by using this information, the lens distortion can be corrected. This is demonstrated both through simulation and correction of real world images." @default.
