The 3D view of gradient vector field and diffused gradient vector field with elastic deformation transformation of a slice cropped from a 3D cell nuclei image. (a). A slice of the 3D image. (b). The original gradient vector field. (c). The diffused gradient flow field with elastic deformation transformation. Obviously, the diffused vector field with elastic deformation transformation smoothly flows toward the central areas of cell nuclei. (d). Zoomed view of (b). (e). Zoomed view of (c).
