Properties
The white top-hat transform returns an image, containing those "objects" or "elements" of an input image that:
- Are "smaller" than the structuring element (i.e., places where the structuring element does not fit in), and
- are brighter than their surroundings.
The black top-hat returns an image, containing the "objects" or "elements" that:
- Are "smaller" than the structuring element, and
- are darker than their surroundings.
The size, or width, of the elements that are extracted by the top-hat transforms can be controlled by the choice of the structuring element . The bigger the latter, the larger the elements extracted.
Both top-hat transforms are images that contain only non-negative values at all pixels.

Famous quotes containing the word properties:
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
