Methods, systems, and computer programs are disclosed for segmenting, from an image, a tooth's pulp region comprising a pulp chamber and root canals. Curvature-based shape recognition is performed at different spatial scales using smoothed versions of the image. An indication of a point or region is received, located in the pulp chamber and referred to as 'seed'. The seed is used as initial segmentation mask. An update procedure, iteratively carried out, comprises: (i) determining candidate image elements for updating the segmentation mask, comprising: (i&#x2212;1) in the first n iteration(s), a grayscale thresholding taking as reference the current segmentation mask; and, (i&#x2212;2) in at least one iteration, taking the curvature-based shape recognition into account; (ii) retaining, among the candidate image elements, a region of connected candidate image elements that comprises the seed; and (iii) using the retained region to update the segmentation mask.
