An image processing system comprising 3D processing means (10, 11) of automatic segmentation of an object using a 3-D deformable Surface Model, further comprising means of real-time interactive adaptation (20) of the Surface Model including user-controlled means of selection (21) of a 2D Data Plane (DP) that intersects the 3-D Surface Model along a 2-D Model Curve (MC); user-actuated means for actuating a Click Point (CP) in said 2-D Data Plane and real-time calculation means for yielding a 3D Correction Surface (G) attached to said Click Point; attract-to-points processing means for pulling the points of the 3D Surface Model, in a 3D neighborhood of a 2D portion of the Model Curve to be modified, towards the 3D Correction Surface; and visualization means for visualizing user-controlled actions. The user may slide the Click Point in the Data Plane, whereby the 3D Surface Model looks like attracted to the Click Point and the Correction Surface. Optionally, the user may modify the shape of the attached 3D Correction Surface, while sliding the Click Point. |
