An Algorithm for Compensating the Effect of Deformations When Using the Shadow Background Method

Abstract

An algorithm for compensating image distortions under the influence of the surface deformation of the background screen when using the shadow background method. The efficiency of the algorithm is confirmed. We experimentally determined the optimal marker to be used for searching on the image. We examined the capabilities of the algorithm in compensating for the shift and rotation of the surface of the background screen with an mean square deviation of not more than 0.43 pixels, determined by cross-correlation processing.
