چکیده

In this paper methods for analysing and processing digitised compressed video newsfeeds are discussed. Due to computing, storage and communication limitations the material has to be processed in compressed form. This creates particular problems which are not encountered when decompressed video material is handled. The methods described allow news editors to directly extract information from the compressed material, creating the possibility that only those video clips which may be of interest need be decompressed. News editors can decide which sections of a newsfeed should be extracted and assembled for a particular news cast. The final cutting can then be done from the original broadcast quality material. This paper reports on results obtained with a joint research project with a commercial television station.

A Content Based Internet Search Engine for Analysis and Archival of MPEG-1 Compressed Newsfeeds

In this paper a specialised search engine for TV news editors as part of a system for analysis and presentation of MPEG compressed newsfeeds is discussed. The editor is supplied with additional material relating to particular news items, which he can, for example, use to prepare the accompanying text of newscasts. The key words for the search engine are extracted automatically from the compress...

Internet Supported Analysis of MPEG Compressed Newsfeeds

In this paper new ideas and algorithms for adapting the workflow for newscast production are presented. The goal is to enable TV news editors to take advantage of the added facilities offered by digital video techniques. Algorithms for the analysis of MPEG compressed videos are presented. These enable a news editor to extract sequences of key frames from newsfeeds. Newsfeeds consist of assemble...

A System for Analysis and Presentation of MPEG Compressed Newsfeeds

In this paper an iterative algorithm for extraction of key frames from digitised MPEG-1 compressed newsfeeds is introduced. Newsfeeds consist of assembled news clips transmitted by news agencies. These are usually recorded in analogue form by subscribing TV stations. Editors analyse the video material through a sequential and time intensive search in order to select sequences which can be used ...

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...

Deblocking Joint Photographic Experts Group Compressed Images via Self-learning Sparse Representation

JPEG is one of the most widely used image compression method, but it causes annoying blocking artifacts at low bit-rates. Sparse representation is an efficient technique which can solve many inverse problems in image processing applications such as denoising and deblocking. In this paper, a post-processing method is proposed for reducing JPEG blocking effects via sparse representation. In this ...
