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. WebThe top-hat filter technique has the following properties: i) Strong background suppression effect. ii) Smoothing effect. The top-hat filter allows for the robust removal of slowly changing background on an array and has become an important tool in many image analysis applications, for instance: i) Morphological sharpening.
