{Simplest case: segmentation into two classes (object/background). {The intensities in each class will be our clusters. {We want to find a threshold such that each pixel on each side of the threshold is closer in intensity to the mean of all pixels on that side of the threshold than to the mean of all pixels on the other side of the threshold.

26.09.2019 · What is Threshold Based Segmentation? Threshold based is a way of segmenting anatomical structures of interest that requires a threshold to be set which describes the grey-scale intensities of the voxels within the region of interest. For instance, in Rhino3DMedical, thresholds can be set such that all voxels values above it will be labeled ...

26.09.2019 · The difference is about locality of the extracted surface: Threshold based segmentation extracts a surface corresponding to the whole set of labeled voxels, while Region Growing extracts only those labeled voxels that are adjacent (and growing from a common seed voxel). Hence, the first mettod is sort of global while the second is local.

Thresholding (image processing) - Wikipedia
https://en.wikipedia.org/wiki/Thresholding_(image_processing)
The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity is less than some fixed constant T (that is, ), or a white pixel if the image intensity is greater than that constant. In the example image on the right, this results in the dark tree becoming completely black, and the white snow becoming completely white.
