Analysis methods of CT-scan images for the characterization of the bone texture: First results

The ultimate objective of the planned work is to propose a way to the characterization of the bone texture from the analysis of CT-scan images. This would assist the discrimination of healthy from pathological subjects. This paper emphasizes a preliminary study concerning the selection of tools for the characterization of the bone texture. The selectivity is lead by the analysis of respective sensitivities of the considered methods. We study here two methods of texture analysis. The first one is based on the fractal geometry whose application to the analysis of texture is well established in literature. The second method is an original one. It is called the "method of the three dimensional relief". (C) 2003 Elsevier Science B.V. All rights reserved.
