Details and Options Details and Options

HighlightImage always generates an 8-bit RGB image.
HighlightImage[image, {{x₁, y₁}, ...}] creates a marker region from the specified positions in the standard image coordinates, where is the bottom-left corner of the image and is the top-right corner of the image.
Different highlighting methods can be specified using the Method option:

	"Blur"	blur the background
	"Boundary"	mark the boundary between foreground and background
	"Brightness"	darken the background
	"CrossMarkers"	highlight specified markers with a cross
	"DiskMarkers"	highlight specified markers with a disk
	"Fade"	fade the background
	"Saturation"	convert the background to gray scale
	"Solid"	replace the foreground by the highlight color
	f	apply f to the background pixels

By default, the most suitable method is used.
With Method->{"Boundary", thickness}, the thickness of the boundary can be specified. By default, thickness=1.
With and methods, can be used to specify the marker radius. By default, radius=2.
HighlightImage takes a option that specifies the color to use in some highlighting methods.
