Lens Correction / Distortion - Paul Bourke - Personal Pages The more lens curvature the greater the constants a x and a y will be, typical value are between 0 (no correction) and 0.1 (wide angle lens). The "||" notation indicates the modulus of a vector, compared to "|" which is absolute value of a scalar. The vec
Lens correction model - PanoTools.org Wiki Lens correction model The panorama tools have a very flexible model to correct for typical geometrical lens errors. Even better, it can often even estimate the correction parameters directly from the images in a panorama. There are a total of 6 parameters
Correcting lens distortion with Photoshop. Although the automated 'Lens Correction' filter's algorithm used by Photoshop CS2 and CS5 will correct barrel distortion and keystoning, care should be used to assure that you are not fixing one problem by exaggerating another. Lens Distortion in Wide Ang

These programs rely on the EXIF information embedded in the digital photograph, providing the make, model and fo-cal length. They are shipped with an extensive camera/lens database, providing the correction parameter
A simple algorithm for correcting lens distortion - Tanner Helland (dot) Com One of the new features in the development branch of my open-source photo editor is a simple tool for correcting lens distortion. I thought I’d share the algorithm I use, in case others find it useful. (There are very few useful examples of lens correctio

Lens Vignetting Correction Algorithm In Digital Cameras Title: Lens vignetting correction algorithm in digital cameras. Abstract: A lens vignetting correction method for use in imaging systems such as digital cameras employs a polynomial correction function F=ar2+br4+c, wherein r is a distance to a center of c
Correction Algorithm of Fish-Eye Lens Image Distortion Based on the Circle Segmentation Approach--《J For the severe distortion problem of fish-eye lens images,a correction algorithm based on circle segmentation approach was proposed.The circular structure of the fish-eye image features is extensively used in the algorithm and the image is split into conc
