Other advanced performance and value features of the two new bundles include the following: bar code recognition, automatic brightness adjustment, automatic image emphasis, dynamic threshold, white-level readings taken directly from paper, automatic separation, noise reduction, auto preview, auto rescan, dither, error diffusion, multi-color dropout, optional flatbed scanning, and color duplex two-sided imaging.
The procedures for applying AMELSBR method are Capacity Evaluation, Minimum Error Replacement and Error Diffusion.
There are two main kinds of halftoning techniques: ordered dithering [5] and error diffusion [5].

Topics discussed include halftone error diffusion methods, visual cryptography for color images, cryptography for multiple secrets, photographic images, probabilistic visual cryptography schemes, cheating prevention, resolving alignment problems, steganography in halftone images, and two-decoding-option image sharing methods.
User controlled dot size and shape using block quantization called quantization and feedback process block error diffusion (Damera-Venkata & Evans, 2001).
Dual 2D-Adaptive enhancement and ADL+ error diffusion halftoning produce reliable monochrome copies of drawings and photos where subtle differences between shades of gray are maintained in the printed output.
It also has 36-bit image capturing processing capabilities for scanning poor quality images, such as a patented two-dimensional adaptive threshold, sharpening, softening, blurring, and the manufacturer's ADL+ error diffusion halftone copying algorithm.
Another quality halftoning method, error diffusion (the concept for which dates from the mid-1970s), Parker said "produces a very nice pattern" but exists simply as an algorithm rather than a screen.
An Edge Enhancement feature in UHQ eliminates the fuzzy look often appearing on transmitted text, graphics, and illustrations, and its Error Diffusion Method provides more depth and clarity of halftones.
More than 256 color gradations are possible with Canon's Photoreal Error Diffusion feature.
Even the amateur operator can be assured quality scans with image enhancement features such as error diffusion and gamma correction.
