By establishing a correspondence between this quantizer and the evenly distributed one, we obtain a new image where the most frequent grey levels are expanded whereas those grey levels with less number of pixels are compressed. | URI: | http://hdl.handle.net/10553/46211 | ISBN: | 978-3-540-63811-7 3540638113 |
