Abstract (sommario):

Local Area Networks (LAN) are destined to play a rapidly increasing part in the transmission and distribution of a wide range of information, and this thesis describes the study of the problems concerning the transmission of coloured images over a particu1ar network, the Cambridge Ring. A colour image station has been developed for the use on the Cambridge Ring. It provides two main services: a high resolution freeze frame transmission and a medium resolution slow-scan image transmission.

Abstract (sommario):

Transmission of images over low speed, low bandwidth channels has several applications. Examples include transmission of remote sensing images, scanning of vast global databases and facsimile transmission of printed material. In progressive image transmission, a low resolution image is first transmitted with as few bits as possible. The resolution of the transmitted image is then improved interactively upon viewer's request. Eventually, an exact copy of the original image is reconstructed. In this thesis, image coding techniques and parallel architectures are first reviewed followed by a revie

Abstract (sommario):

Progressive image transmission, where an image builds up gradually, is gaining popularity in image database browsing applications. In these applications, a user might have to reject a large number of unwanted images before selecting the desired one. In such a case, the time required to identify the image contents becomes very important. In this thesis, we present a novel progressive image transmission technique based on a representation by segmentation. The technique preserves edges at low bit rates and is biased toward fast identification. An image is segmented into regions having constant in

Abstract (sommario):

This thesis provides a comparative analysis of sentencing patterns in two time periods separated by seventeen years. Research of this type has not been attempted previously, due to the limited availability of historical sentencing data. Using statistics obtained from the Royal Canadian Mounted Police's Fingerprint System from 1983--1984 and the Canadian Centre for Justice Statistics' Adult Criminal Court Survey for 1999--2000, this study examines whether recommendations made by various federal inquiries into sentencing have affected judicial decision-making at the trial court level.

Abstract (sommario):

As the need for digital libraries, especially genealogical libraries, continues to rise, the need for efficient document image compression is becoming more and more apparent. In addition, because many digital library users access them from dial-up Internet connections, efficient strategies for compression and progressive transmission become essential to facilitate browsing operations. To meet this need, we developed a novel method for representing document images in a parametric form. Like other “hybrid" image compression operations, the Contour Encoded Compression and Transmission (CECAT) sys

This is followed by a review of the various techniques reported in the literature for achieving scalable image compression. We then investigate the algorithms for scalable image compression within the framework of JPEG standard. An extension to the hierarchical mode algorithm of JPEG is presented which provides an improved coding performance. This is followed by evaluation of the performance of these algorithms for image transmission over ATM networks. JPEG pro

This thesis involves systems for virtual presence in remote locations, a field referred to as telepresence. Recent image-based representations such as Google map's street view provide a familiar example. Several areas of research are open; such image-based representations are huge in size and the necessity to compress data efficiently for storage is inevitable. On the other hand, users are usually located in remote areas, and thus efficient transmission of the visual information is another issue of great importance.

Abstract (sommario):

Video coding standards such as H.264 AVC (Advanced Video Coding) rely on predictive coding to achieve high compression efficiency. Predictive coding consists of predicting each frame using preceding frames. However, predictive coding incurs a cost when transmitting over unreliable networks: frames are no longer independent and the loss of data in one frame may affect future frames. In this thesis, we study the effectiveness of Flexible Macroblock Ordering (FMO) in mitigating the effect of errors on the decoded video and propose solutions to improve the error concealment on H.264 decoders.

Abstract (sommario):

Two interesting new methods for direct image transmission via optical communication channels are presented. In the first of these, the images are transmitted via a serial optical link using phase only encoding and decoding of the image. This is achieved by encoding the image using a set of binary phase sequences and sending the sum of the field from all the pixels through the link. The image is reconstructed by first spatially separating the beam into output pixels and impressing phase sequences conjugate to those used to encode the image onto each pixel. Then the output pixels are combined wi

The challenge of restoring such atmospheric effects, usually referred to as “dehazing”, from single image mainly comes from the double uncertainty of scene depth and scene radiance. Approximation of the transmission, which encodes the scene depth information, is the most significant step to solve the dehazing problem.
