1. An adaptive image region partition method using a computer or processor to carry out the steps of: a) Input a component labeled image and its associated characteristics for each component; b) Perform an adaptive two pass ZOI creation method using the component labeled image and component characteristics to create an adaptive ZOI image using a length function I wherein a component specific weighting factor w is applied to the length function to generated a component weighted length: 
 l [( i,j ), Z ( i,j )]= l ( i,j )* w ( Z ( i,j )) wherein w is a general function of component characteristics that is related to one of component size, component confidence, or types of components and Z(i,j) is component labeled image value at image position (i,j).
