| "In this thesis, several eight-frame algorithms for their use in phase shifting profilometry and their application for the analysis of semi fossilized materials are presented. All algorithms are obtained from a set of two-frame algorithms and designed to compensate common errors such as phase shift detuning and bias errors. The processed images make it possible to obtain the distribution of height (topography) of the object, with the advantage that this type of structured light is ideal for retaining the intrinsic biological properties of fossils (this property could be especially useful in cases where it is crucial to obtain high quality images from biological samples that include sensitive molecules, as is the case with ancient DNA). In addition, because the availability of fossil samples is limited (fossilization is a rare phenomenon, thought to preserve only 1 to 5% of total biodiversity) and fossils preserve key biological information, it is essential to conserve as many morphological features as possible (e.g., teeth and mandibles for rodents). This work provides the tools to create a 3D database for the study of morphology of semi-fossilized specimens using an optical nondestructive testing technique. The implementation of protocols and computational algorithms developed in this study in conjunction with various optical methods can be used in studies of systematics, evolution, ecology, genetics and geographical distribution for various biological groups." | |
