With binary images, this smoothes objects and removes isolated pixels. Close Performs a dilation operation, followed by erosion. With binary images, this smoothes objects and fills in small holes. Allows you to specify the number of times erosion, dilation, opening, and closing are performed. The default is one.
Outline Generates a one pixel wide outline of black objects in a binary image.
Skeletonize Repeatably removes pixels from the edges of objects in a binary image until they are reduced to single pixel wide skeletons. Objects are assummed to be black and backgound white. Requires a binary image as input. The UEPs represent the centers of particles that would be separated by segmentation. The UEP's gray value is equal to the radius of the inscribed circle of the corresponding particle.
