We propose an image-based 3D modeling method based on a multi-resolution evolution of a level-set of a volumetric function, steered by the texture mismatch between views. A key feature of this approach is that it operates in an adaptive multi-resolution fashion, which boosts up the computational efficiency.

A Hypercard-based software tool developed to provide help in the identification of biological specimens is presented. The package implements a matching algorithm that compares alphanumeric strings and runs on Macintosh computers, though its simple architecture can be transferred to other computers and/or other programming environments. The overall performance of the program and its easy customization to specific problems are demonstrated by discussing at length one application in the field of earthworm identification.
