New method for height estimation of subjects represented in photograms taken from video surveillance systems

The article describes a method developed and applied by the authors for the purpose of determining the height of subjects taped on video surveillance systems. The determination of height is obtained by developing a virtual telecamera having the same characteristics of the video surveillance system with which the images have been shot. The results demonstrate that height is a parameter that can be accurately estimated with the method proposed, in the experimental conditions described, and consequently, can be utilized in probatory inquiry.
