Digital Compression for Television Pictures
The word "compression" has become very fascinating now days and is being linked with digital technology in general. The advent of digital technology and incorporation of its enhanced capabilities into field of TV technology made the "compression" quite mysterious. It is not only digital domain where recently the compression techniques have started being applied. It is applicable to analog domai...
متن کاملDigital Color Restoration of Faded Motion Pictures
The cinematographic documents recorded on chemical support represent a significant cultural heritage. These films, however, are often very damaged. Using powerful multimedia platforms, motion pictures can be digitized at a high resolution, processed and reproduced, thus allowing a digital restoration of old films. We present in this paper a technique to restore faded color films. This method co...
متن کاملA theory of binary digital pictures
We study 2and 3-dimensional digital geometry in the context of almost arbitrary adjacency relations. (Previous authors have based their work on particular adjacency relations.) We define a binary digital picture to be a pair whose components are a set of lattice-points and an adjacency relation on the whole lattice. We show how a wide class of digital pictures have natural "continuous analogs."...
متن کاملA Robust Algorithm for Information Hiding in Digital Pictures
A problem inherent in information hiding techniques for digital images is that of alignment during data extraction. This alignment problem can be solved using a search approach where a combination of coarse orientation detection, random search and gradient descent methods are employed. When used in conjunction with the Patch Track algorithm, it is possible to create an information hiding and re...
متن کاملSession 9: Natural Language Processings
Traditional approaches to interpretation in natural language processing typically fall into one of three classes: syntaxdriven, semantics-driven, or frame/task based. Syntaxdriven approaches use a domain-independent grammar to drive the interpretation process and produce a global parse of the input, accounting for each word of the sentence. Semantics-driven approaches use knowledge about the ca...
