DeleteSmallComponents

DeleteSmallComponents[image]
replaces small connected components in a binary image image with background pixels.

DeleteSmallComponents[m]
replaces positive integers in a label matrix m with

if their tally is small.

replaces components consisting of n or less elements.

DeleteSmallComponents by default treats all eight pixels surrounding a given pixel as adjacent.

The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.

DeleteSmallComponents[input, Method->method] specifies the method to use to determine the pixel size of small components.

	"Cluster"	cluster variance maximization (Otsu's algorithm)
	"Mean"	use the mean of component sizes as the threshold
	"Median"	use the median of component sizes as the threshold
