Recent Advances in Digital Halftoning and Inverse Halftoning Methods
Halftoning is the rendition of continuous-tone pictures on displays, paper or other media that are capable of producing only two levels. In digital halftoning, we perform the gray scale to bilevel conversion digitally using software or hardware. In the last 3 decades, several algorithms have evolved for halftoning. Examples of algorithms include ordered dither, error diffusion, blue noise masks...
متن کاملModel-based digital image halftoning using iterative reduced-complexity grid message-passing algorithm
An iterative grid message-passing algorithm for model-based digital image halftoning is introduced. Based on the standard message-passing algorithm on the grid graphical model, the algorithm is designed to suboptimally solve general two-dimensional (2D) digital least metric (DLM) problems and is found to be very successful (i.e., nearly optimal) for 2D data detection in page-oriented optical-me...
متن کاملDigital halftoning algorithm using visual-optimized binary patterns
The digital halftoning is a gray level rendition in the devices that have the limited gray representation capabilities. The major evaluation points of the digital halftoning methods are the image quality and the processing speed. A new halftoning method using non-thresholding process is proposed, which simply constructs a halftoning database to achieve real time halftoning as well as optimal im...
متن کاملSteganalysis of Data Hiding via Halftoning and Coordinate Projection
Steganography is the art of hiding and transmitting data through apparently innocuous carriers in an effort to conceal the existence of the data. A lot of steganography algorithms have been proposed recently. Many of them use the digital image data as a carrier. In data hiding scheme of halftoning and coordinate projection, still image data is used as a carrier, and the data of carrier image ar...
متن کاملAMÕFM halftoning: digital halftoning through simultaneous modulation of dot size and dot density
Conventional digital halftoning approaches function by modulating either the dot size [amplitude modulation (AM)] or the dot density [frequency modulation (FM)]. Generally, AM halftoning methods have the advantage of low computation and good print stability, while FM halftoning methods typically have higher spatial resolution and resistance to moiré artifacts. In this paper, we present a new cl...
