Red hand and steps of the proposed method. (a) Processed image. (b) Moving points, fitting ellipse (indicated by red dots and a red ellipse), and center of mass (indicated by a red square). (c) Threshold image I Th in the ROI defined from the fitting ellipse. (d) Result obtained after mathematical morphology operations. (e) I f-square ROI whose height is the maximum Ferret diameter of the hand. (f) I c, obtained from Roberts linear filtering, containing the expected hand contour.
