This study examined the efficacy of three enhancement software products for use in the analysis of photographic evidence.
Abstract
A laboratory protocol using three enhancement software products has been developed for the analysis of photographic evidence. Photographs of two bite marks produced by different subjects and two wax registration impressions were scaled to 1:1 using Photoshop 6.0 (Adobe Software, Inc., San Jose, CA). The images were then enhanced with Lucis 4.2.1 (Image Content Technology, Groton, CT), a software product that reveals variations in luminance and displays the patterns of contrast present in an image. After Lucis enhancement, the images were analyzed with Measurement of Internal Consistency Software 2.0 (MICS) (LumenIQ, Inc., Bellingham, WA), which allows two-dimensional photographic images to be viewed in a third dimension. The 1:1 enhanced images of the bite impressions were compared to wax registration impressions using an acetate overlay comparison method. Detail in the bite pattern was revealed and clarified by enhancement with both Lucis and MICS. The benefit of the protocol lies in its ability to view physical evidence in three dimensions with various viewing positions. Figures, tables, and references (Published Abstract)
