Segmentation > E-M Threshold
Selects pixels if they are within a region in which none of its pixel have fallen below a threshold pixel value distance from the nearest local minimum.
- 8-pixel: Uses 8-pixel connectivity (face-based) to determine local minima as the basis for the E-M threshold
- 4-pixel: Uses 4-pixel (face+corner-based) connectivity to determine local minima as the basis for the E-M threshold
Sets the maximum difference threshold pixel intensities can be from the nearest local minima in order to grouped into that minima’s region
