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:
“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)
“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)
