Abstract :
This paper shows the influence of computed tomography slice thickness on textural parameters by simulating realistic images issued from: (1) a 3D model of vascular tree, with structural and functional features and in which angiogenesis is related to the organ growth; (2) a projection/reconstruction process using fast Fourier transform. Texture analysis is performed by means of second-order statistics and gradient based methods.
