Develop prototype software for detection of tread ridges in outsole imagery to facilitate the extraction and analysis of tread patterns. The method is now being adapted to better handle the specific shading patterns observed in outsole images and impressions which provide cues to 3D shape, in particular which components of the tread (e.g. ridges) are likely to leave behind impressions or prints.
