There has been a growing interest in recent years in developing real-time voice and fax communication software for use over the Internet. This paper discusses the design of an Internet Telephony Gateway (ITG) that is used to support the delivery of fax and/or voice services through the Internet to conventional telephones and fax machines on the Public Switched Telephone Network (PSTN). The inte...

We consider the problem of classifying a telephone line as either a voice or fax telephone line based on its long-distance calling patterns (i.e., the time of day and duration of its long distance calls) and based on knowledge about other lines with which calls are placed. We show that both kinds of information are important. In particular, neither choosing new learning algorithms nor collectin...

This document describes the TIFF (Tag Image File Format) representation of image data specified by the ITU-T Recommendations for black-and-white and color facsimile. This file format specification is commonly known as TIFF-FX. It formally defines minimal, extended and lossless JBIG modes (Profiles S, F, J) for black-and-white fax, and base JPEG, lossless JBIG and Mixed Raster Content modes (Pro...

We have implemented approaches to compressing and decompressing a sequence of head-and-shoulders images that trade off the data rate, picture quality, computational complexity and latency. All these approaches are transform-free and pixel-based; some of them also involve no motion compensation and hence are free of block-based artifacts. We compare the magnitude of the intensity of each pixel s...

We describe an experiment in which a blind person places arbitrary printed pages in a FAX machine and soon afterwards hears the contents read out loud over the telephone by a synthesized voice. This study focuses on technical issues including the accuracy achievable by stateof-the-art optical character recognition operating on FAX images, methods to improve the intelligibility of synthesized sp...
