In
1991, an image processing technique was proposed to make local
contrast independent of intensity. This technique was successfully
applied in mammography. We will describe an experiment in which
we tested the technique by imaging tissue-equivalent blocs and
artificial micro-calcifications on a digital mammography machine.
This test led us to propose a modified technique. After explaining
the original and modified techniques, we will discuss whether
text detection in video might be improved by the application of
a similar technique. Joint work with O. Gurun, MS, P. Fatouros,
Ph.D., E. Shaw de Paredes, MD Medical College of Virginia.
