This function works in the same way as normal erosion. Structures in the input image are reduced. Thin connections between regions are separated. The difference between this function and normal erosion is that structures are eroded until they would be deleted by the next erosion step. With erosion, the pixel in question is set to the gray value 0 (black) in the resulting image. For regions (pixels) at the image edge, the assumption is that the pixels outside the image are white.

Parameter

Description

Structure Element

Selects the preferred direction of morphological change (e.g. Cross, Diagonal).

Count

Sets the number of repetitions. This means that the function is applied a number of times in succession to the filtering result. This increases the effect accordingly.

Converge

Activated: The function is automatically repeated until all regions will be deleted by the next erosion step.
