چکیده

Photographic supra-projection is a complex and uncertain process that aims at identifying a person by overlaying a photograph and a model of the skull found. The more accurate the skull model is the more reliable the identification decision will be. Usually, forensics are obliged to perform a manual and time consuming process in order to obtain the model of the scanned forensic object. At least semiautomatic methods are demanded by these experts to assist them with this task. Our contribution aims to propose an evolutionary-based image registration methodology for the skull 3D model building problem. Experiments are performed over thirty two problem instances corresponding to a semiautomatic and fully automatic real skull model reconstruction.

Automatic Feature Extraction from 3D Range Images of Skulls

The extraction of a representative set of features has always been a challenging research topic in image analysis. This interest is even more important when dealing with 3D images. The huge size of these datasets together with the complexity of the tasks where they are needed demand new approaches to the feature extraction problem. The need of an automatic procedure is specially important in ma...

A scatter search-based technique for pair-wise 3D range image registration in forensic anthropology

Different tasks in forensic anthropology require the use of three-dimensional models of forensic objects (skulls, bones, corpses, etc) captured by 3D range scanners. Since a whole object cannot be completely scanned with a single image, multiple scans from different views are needed to supply the information to construct the 3D model. Range image registration methods study the accurate integrat...

Automatic Sex Determination of Skulls Based on a Statistical Shape Model

Sex determination from skeletons is an important research subject in forensic medicine. Previous skeletal sex assessments are through subjective visual analysis by anthropologists or metric analysis of sexually dimorphic features. In this work, we present an automatic sex determination method for 3D digital skulls, in which a statistical shape model for skulls is constructed, which projects the...

A comparative study of state-of-the-art evolutionary image registration methods for 3D modelingq

Image registration (IR) aims to find a transformation between two or more images acquired under different conditions. This problem has been established as a very active research field in computer vision during the last few decades. IR has been applied to a high number of real-world problems ranging from remote sensing to medical imaging, artificial vision, and computer-aided design. Recently, t...
