Embedding Digital Hidden Data into Hardcopy,e hidden digital data into a printed text document with the ability to extract this data during scanning. Our approaches are based on the intrusion of clusters with small black dots (patterns) arranged in predefined structures into the document. The patterns of the dots and their positions were sele

On-the-Fly Microtext Generation,ce printer is required. In this chapter, we present a method for on-the-fly microtext generation. In general, the approach is applicable to any language and a wide set of typefaces. The technique consists of rendering a symbol to an intermediate image and creating a skeleton by iterative thinning an

Toner Saving by Random Perforation,ving approaches have two main drawbacks: the appearance of the hard copy in the toner saving mode is worse compared with the normal mode and the processing of the whole rendered page bitmap requires significant computational costs. We describe a method that entails the addition of small holes of var

Integral Printing,t. It more specifically relates to creating an illusion in the eyes of the observers, such that they think they see a 3D object with volume. This is done on the basis of digital images and integral photographs (.) that are capable of being reproduced as colour 3D images. Practically speaking, a lens

How TNC-Friendly Is Development Policy? pages can contain various types of degradation effects, such as page skew, page warping and the presence of a shadow near the spine area. The correction procedure described herein is capable of detecting whether part of the page is outside the scanning area and would not appear in the image and wil

How Have TNCs Changed in the Last 50 Years?business cards. Card images differ significantly from common document images and conventional approaches developed for text document image processing do not operate well for card images. For single-page and duplex printing, our technique provides a sophisticated layout of images for both sides of a
