3D Winding Number: Theory and Application to Medical Imaging
Figure 2
Follicle detection. The red dots highlight the detected minima. (a) The image shows detected minima at scale . The image is very noisy, and the algorithm detects also the minima corresponding to noisy grains (false positives). (b) The image shows minima detected at scale . The arrow shows a minimum detected outside the ovarian tissue (false positive), whereas the red dot inside the ovarian tissue corresponds to the center of a follicle. (c) In this image, the false positive outside the ovarian boundaries has been filtered out.
