1. A method of stabilizing a sequence of infrared (IR) images captured using an infrared (IR) imaging system, the method comprising: generating edge information representations of selected captured IR images in said sequence; for each generated edge information representation, generating a second representation having a reduced amount of information compared to the edge information representation; determining displacements between captured IR images in relation to previous IR images in said sequence based on a comparison between said second representations of IR images; and generating a stabilized sequence of IR images by shifting said captured IR images based on said determined displacements.
