FIELD: control-measuring criminalistics equipment, possible use for determining remoteness of sweat-fat hand marks.;SUBSTANCE: method for determining remoteness of sweat-fat hand mark includes detection of mark, for example by means of dactyloscopic powder, photometry of image of papillary lines in all mark points, digitization of image of mark together with background surrounding it, construction of brightness histogram relatively to mark and relatively to background, determining of average quadratic brightness deviation relatively to mark and relatively to background, production of their relation and comparison to calibration curve produced using a test object.;EFFECT: increased precision when determining remoteness of mark.;7 dwg
