MethodsTraditional gradient force, gradient plus pressure force and gradient vector flow force were used in active contour models to segment malleus, incus, eardrum and some shared surface images. The segmentation results were compared. ResultsBoth the gradient force and the GVF force resulted in satisfactory results when the initial contours were close to the boundary.
