Halftoning and inverse halftoning algorithms are very important image processing tools, widely used in the development of digital printers, scanners, steganography and image authentication systems. Because such applications require to obtain high quality gray scale images from its halftone versions, the development of efficient inverse halftoning algorithms, that be able to provide gray scale images...
Halftoning and inverse halftoning algorithms are very important image processing tools that have been widely used in digital printers, scanners, steganography and image authentication systems. Because such applications require obtaining high quality gray scale images from its halftoning versions, several inverse halftoning algorithms have been proposed during the last several years, which provide...
Digital halftoning is an active research theme, which can be applied in many fields of image processing. There are several methods with different characteristics. In digital halftoning, we perform the gray-scale to bi-level conversion using software or hardware and the inverse halftoning is a reconstruction technique of a gray-scale image from its halftone version. This paper proposes a new method...
