abstract = "This work introduces a residual operator called ultimate attribute
leveling. We also present an efficient algorithm for ultimate
attribute leveling computation by using a structure called tree of
shapes. Our algorithm for computating ultimate attribute leveling
is based on the fact (proved in this work) that levelings can be
obtained by pruning nodes from the tree of shapes. This is a novel
result, since so far it is known that levelings can be obtained
from component trees. Finally, we propose the use of ultimate
attribute leveling with shape information to extract contrast
using a priori knowledge of an application. Experimental results
applied to text location show the potentiality of using ultimate
attribute leveling with shape information for solving problems in
image processing area.",
