3D Winding Number: Theory and Application to Medical Imaging
Figure 1
Critical point refinement. (a) A continuum Gaussian signal in 1 dimension and the corresponding sampled signal. The sampled signal shows maxima at two nearby positions (points in red), which are at different locations from the real maximum (point in green). (b) Rasterized version of a 2-dimensional Gaussian signal. Red points are the retrieved maxima, whereas the green point is the true maximum obtained after the refinement.
