Context-based arithmetic encoding of 2D shape sequences
Noel Brady,F. Bossen,Noel Murphy +2 more
TL;DR: Context-based arithmetic encoding, as used in JBIG, is utilised within a block-based framework and further extended in order to make efficient use of temporal prediction.
Evaluating and combining digital video shot boundary detection algorithms
TL;DR: This paper examines a variety of automatic techniques for shot boundary detection that are implemented and evaluated on a baseline of 720,000 frames (8 hours) of broadcast television and examines the benefits in accuracy and performance that this brought to the system.
Journal ArticleDOI
Automatic TV advertisement detection from MPEG bitstream
TL;DR: Progress made in the development of the idea into an advertisement detector system that automatically detects the commercial breaks from the bitstream of digitally captured television broadcasts is reported on.
Proceedings ArticleDOI
Evaluation of automatic shot boundary detection on a large video test suite
TL;DR: It is observed that the selection of similarity thresholds for determining shot boundaries in such broadcast video is difficult and necessitates the development of systems that employ adaptive thresholding in order to address the huge variation of characteristics prevalent in TV broadcast video.
Region-based segmentation of images using syntactic visual features
TL;DR: It is demonstrated that syntactic features provide a reliable basis for region merging criteria which prevent formation of regions spanning more than one semantic object, thereby significantly improving the perceptual quality of the output segmentation.
