Abstract

We present an image processing method which can be useful for objects analysis dealing with life and earth sciences. We use a non-contact optical sensor based upon laser triangulation to determine depth of 3D surfaces of the object under consideration. The 3D surface constitutes an image which can be characterized by multiresolution analysis. We applied this system to the study of bivalve shell surface (Unio sp. Recent Atlantic, Holocene) to determine the influence of the environment on its growth rate. Our algorithm is based upon the wavelet transform.
