Dithered GMD Transform Coding

Compaction of ordered dithered images with arithmetic coding

Ordered dither is considered to be a simple and effective method among all halftoning techniques. In this paper, compaction of ordered dithered images using arithmetic coding is studied. A preprocessor referred to as pixel interleaving (i.e., grouping pixels with similar dithering thresholds) is employed in such a way that dithered images can be efficiently coded with the JBIG1 code and high co...

Network Source Coding Using Entropy Constrained Dithered Quantization

Discrete Dithered Desynchronization

This paper introduces the Discrete Dithered Desynchronization (DSYNC ) algorithm which is a decentralized Time Division Multiple Access (TDMA) technique in which a set of network nodes computes iteratively a conflict-free schedule so that each node obtains a portion of a frame that is an integer multiple of a fixed slot size. The algorithm is inspired by the dynamics of Pulse Coupled Oscillator...

The integration of concepts from logic and deduction into databases and knowledge bases has created the eld of deductive databases. Logic programming provides a powerful declarative language for accessing and maintaining knowledge in databases. Techniques from relational databases and automated deduction are useful for achieving e cient retrieval and reasoning in large knowledge bases. Thus, de...

The approach to visual interfaces outlined in this paper treats user inputs such as mouse clicks, menu selections, etc. not as invocations of methods that can be executed without regarding the dialogue context, but instead as dialogue acts expressing discourse goals of the user. The system can respond in a more flexible way by taking into account the pragmatic and semantic aspects of the user’s...
