Interactive Compression of Digital Data
If we can use previous knowledge of the source (or the knowledge of a source that is correlated to the one we want to compress) to exploit the compression process then we can have significant gains in compression. By doing this in the fundamental source coding theorem we can substitute entropy with conditional entropy and we have a new theoretical limit that allows for better compression. To do...
متن کاملUsing Interactive Search Elements in Digital Libraries
Background and Aim: Interaction in a digital library help users locating and accessing information and also assist them in creating knowledge, better perception, problem solving and recognition of dimension of resources. This paper tries to identify and introduce the components and elements that are used in interaction between user and system in search and retrieval of information in digital li...
متن کاملCompression of digital video data using
A vector quantizer based on artiicial neural networks is developed for use in digital video data compression applications. A series of experiments investigating the edge performance of various distortion measures and experiments exploring various vector sizes are presented. The paper then describes a diierential vector quantizer which preserves edge features and an adaptive algorithm, Frequency...
متن کاملInteractive Art Analysis Based on Baudrillard’s Hyper reality Theory, a Case Study of Digital Interactive installation
The contemporary philosopher Jean Baudrillard, one of the postmodernism theorists, considers representation in the contemporary world as a factor in the disappearance of reality. In his view, the main feature of new arts is not the expression of artistic beauty, but communication with the audience and expression of the artist’s ideas. In interactive art, the presence and role of the audience in...
متن کاملScattered Data Coding in Digital Image Compression
This paper concerns digital image compression using adaptive thinning algorithms. Adaptive thinning is a recursive point removal scheme which works with decremental Delaunay triangulations. When applied to digital images, adaptive thinning returns a scattered set of most significant pixels. This requires efficient and customized methods for coding these pixels (but not their connectivities). To...
