Single-Image Vignetting Correction from Gradient Distribution Symmetries
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Yuanjie Zheng,Stephen Lin,Sing Bing Kang,Rui Xiao,James C. Gee,Chandra Kambhamettu
Issue Date:June 2013
pp. 1480-1494
We present novel techniques for single-image vignetting correction based on symmetries of two forms of image gradients: semicircular tangential gradients (SCTG) and radial gradients (RG). For a given image pixel, an SCTG is an image gradient along the tang...
