The invention relates to an image processing method for the segmentation of a three dimensional object in a three dimensional image including an operation of mapping a three dimensional mesh model onto said three dimensional object comprising steps of acquiring a tri-dimensional image of an object of interest to be segmented; generating a Mesh Model, formed of cells that can be decomposed into triangles; deforming the Mesh Model in order to map said Mesh Model onto said object of interest; estimating the gradient flow value or a gradient derived measure level of the gradient vector field that passes through the cell surface area of a predetermined number of cells of the Mesh Model; and assessing the goodness of fitness of the Mesh Model according to the proportion of cells for which the gradient flow value or gradient derived measure level reaches at least a predetermined level called fitness threshold. The gradient flow value or gradient derived measure level is color coded to display a color coded image of the Mesh Model for visual assessment of the goodness of fitness.
