Enforcing Consistency of Image Gains in Panoramic Mosaics
Ricardo Galego, Ricardo Poley Martins Ferreira, Alexandre J. M. Bernardino, José António Gaspar · 2011
In this paper we propose a methodology for normalizing the images gains in a mosaicked representation of a scene imaged by a pan-tilt camera. The normalization is based on assuming that one image has unit gain and then estimating, and filtering, the relative gains of all the other images, using the known geometry of the pan and tilt camera to find corresponding points (color values). Experiments with real images show that a mosaic built with image gains normalization has lesser visible seams at the borders of image stitching.
