An adaptive inverse halftoning algorithm
نویسندگان
چکیده
A class of inverse halftoning algorithms that recovers grayscale (continuous-tone) images from halftone images is proposed. The basic structure is an optimized linear filter. Then, a properly designed adaptive postprocessor is employed to enhance the recovered image quality. Finally, a multistage space-varying algorithm is developed that uses the basic linear filter structure as before but with spatially adaptive parameters.

Fast 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 کاملInverse halftoning and kernel estimation for error diffusion
Two different approaches in the inverse halftoning of error-diffused images are considered. The first approach uses linear filtering and statistical smoothing that reconstructs a gray-scale image from a given error-diffused image. The second approach can be viewed as a projection operation, where one assumes the error diffusion kernel is known, and finds a gray-scale image that will be halftone...
متن کاملHybrid inverse halftoning using adaptive filtering
We propose a novel fast inverse halftoning technique using a combination of spatial varying filtering and spatial invariant filtering. The proposed algorithm is significantly simpler than most existing algorithms. Without explicit edge region classification, the proposed spatial varying filter is shown to be capable of preserving edges effectively.

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...
