متن کاملLook-up table (LUT) method for inverse halftoning
In this paper we propose look-up table (LUT) based methods for inverse halftoning of images. The LUT for inverse halftoning is obtained from the histogram gathered from a few sample halftone images and corresponding original images. The method is extremely fast (no filtering is required) and the PSNR and visual image quality achieved is comparable to the best methods known for inverse halftonin...
متن کاملTemplate selection for LUT inverse halftoning and application to color halftones
In a recent paper we have proposed a method for inverse halftoning of monochrome images. It is a Look Up Table (LUT) based method, obtained from the histogram gathered from a few sample halftone images and corresponding original images. The method is extremely fast (no ltering is required) and the image quality achieved is comparable to the best methods known for inverse halftoning. The method ...
متن کاملFast ad-hoc inverse halftoning using adaptive filtering
We propose a novel fast inverse halftoning technique using an adaptive spatial varying filtering. The proposed algorithm is significantly simpler than most existing algorithms while achieving a PSNR close to that of the set theoretic POCS.
متن کاملRecent 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...
