Parameter Description

Parameter Description

Center Type

Description: This parameter is used to set the method to calculate the center point of the non-zero pixel regions in the mask image.

Value list: MassCenter, BoundingBoxCenter

  • MassCenter: Calculate the geometric center of a region based on the positions of all non-zero pixels in the mask.

  • BoundingBoxCenter: Calculate the center of the minimum bounding rectangle of non-zero pixel regions in the mask by the bounding rectangle center method.

Default value: MassCenter
