9.1 Introduction
Morphology, or morphology for short, is a branch of image processing which is particularly useful for
analyzing shapes in images.9.2 Basic ideas
The theory of mathematical morphology can be developed in many different ways.Reflection
If  
is set of pixels, then its reflection, denoted  
, is obtained by reflecting  
in the origin:       	        
 	     
   
 
 
For examples, in figure 9.2, the open and closed circles form sets which are reflections oWe shall develop basic morphological tools for investigation of binary
images, and then show how to extend these tools to greyscale images.Translation
Suppose that  
is a set of pixels in a binary image, and     	     

is a particular coordinate point.
