The ability to visually perceive three dimensions is an important advantage for adaptation to the environment. Bearing this in mind, different techniques and technologies have been developed that allow the replication of this phenomenon from synthetic images. Self-stereograms are a method for the display of images with stereoscopic depth with characteristics that make it possible to implement in areas where other techniques can not be applied. The construction of these images is achieved thanks to computational routines among which the proposal by Thimbleby et al. . Although its effectiveness is widely known, this routine was evaluated because, it is necessary to have more and more evidence of the impact it has on the coded scene in order to identify further improvements. For the evaluation we propose the comparison of the original depth map and the one obtained from the reconstruction process of the scene from a self-stereogram constructed with the algorithm in question. It was observed, among other things, that the routine introduces a deformation in the z-axis.
