The invention relates to a device and a method for segmenting objects in an image. The method comprises steps for: the approximate definition of a contour external to the object to be segmented, said contour including a plurality of so-called control points, the determination of a vicinity of candidate points in the vicinity of each control point, the determination of an energy associated with each candidate point in the vicinity of each control point, the convergence of each of the control points (Vi) towards the candidate point, which minimizes said energy, so providing an estimated contour of the object to be segmented. According to the invention, the energy associated with each candidate point includes a colour discrimination term.
Method of segmenting objects in an image for providing an estimated contour of said object to be segmented comprising steps for:
Method according to claim l, including the step of automatically calculating a contour inscribed in the estimated contour, and a contour circumscribed around the estimated contour, such that the inscribed contour is internal to the object be segmented and the circumscribed contour is external to the object to be segmented.
Device for segmenting objects in an image providing an estimated contour of said object to be segmented comprising:
