Multiscale analysis of 3D surface image: application to clam shell characterization

摘要

Abstract: We present an image processing method which can beuseful for objects analysis dealing with life and earthsciences. We use a non-contact optical sensor basedupon laser triangulation to determine depth of 3Dsurfaces of the object under consideration. The 3Dsurface constitutes an image which can be characterizedby multiresolution analysis. We applied this system tothe study of bivalve shell surface (Unio sp. RecentAtlantic, Holocene) to determine the influence of theenvironment on its growth rate. Our algorithm is basedupon the wavelet transform. !17
