Morphology Top Hat

Mathematical morphology is a method of processing digital images on the basis of shape. Morphing is available during the working over images. Morphology Top Hat is implemented by applying the opening operator to the image, then by subtracting the result from the original one. The applying of Top Hat shows the bright peaks in the image.

Radius and shape of a structuring element for the erode and dilate operators are specified by the correspoding controls.
