Figure 3

Automatic detection of the soma. Panel A shows the maximum projection of a neuron imaged from fluorescent microscopy. Panel B illustrates the maximum response orientation components of the image (directions are color-coded) computed using the continuous shearlet decomposition at a single scale. Note that similar or slowly-changing colors are located along the neurites, unlike the soma region where there are no dominant orientations, that is, directional components vary randomly creating a white noise pattern. Using the directional ratio, we can accurately segment the soma from the rest of the structure in the image (Panel C).
