Methods of estimating a bare body shape from a concealed scan of the body

Methods are disclosed for generating a training dataset of concealed shapes and corresponding unveiled shapes of a body for training a neural network . These methods may include generating with the aid of computing means a first dataset comprising a plurality of first surface representations representative of a plurality of bare shapes of a plurality of bodies . The plurality of bare shapes are concealed virtually by means of a computer implemented program in order to obtain a plurality of simulated concealed shapes of the plurality of bodies . The plurality of simulated concealed shapes are applied to a scanning simulator , the scanning simulator generating a second dataset comprising a plurality of second surface representations representative of the plurality of simulated concealed shapes .
