A fuzzy theoretic approach for video segmentation using syntactic features

TL;DR: Experimental results have shown that the proposed scheme for fuzzification of the frame-to-frame property difference values using the Rayleigh distribution can detect changes reliably.
Abstract: This paper is concerned with the development of a fuzzy-logic-based framework for segmentation of video sequences. We have proposed a scheme for fuzzification of the frame-to-frame property difference values using the Rayleigh distribution. The difference values have been characterized by fuzzy terms like small, significant, large, etc. These terms have been used to design fuzzy rules for detecting abrupt changes and gradual changes. Fuzzy rules have provided a mechanism for integrating evidences based on different properties. The decompositional inference strategy has been used for fuzzy reasoning over the set of fuzzy rules. Gradual changes have been further classified as fade-in, fade-out and others (including dissolves, wipes, etc). Experimental results have shown that the proposed scheme can detect changes reliably.

TL;DR: This paper proposes a new and effective shot boundary detection (SBD) method to detect cut transition (CT) and gradual transition (GT) and uses singular value decomposition (SVD) to reduce the dimension of the feature space to save computing overhead.
Abstract: Shots are the basic unit of video. Shot boundary detection is a pre-task for video semantic analysis and video retrieval. In this paper we propose a new and effective shot boundary detection (SBD) method to detect cut transition (CT) and gradual transition (GT). By introducing the selection mechanism of candidate segment, a large number of non-boundary frames are avoided. We extract the hue-saturation-value (HSV) features of each frame and use singular value decomposition (SVD) to reduce the dimension of the feature space to save computing overhead. In the SBD stage, we propose a scheme based on accumulative distance. By calculating the maximum distance and accumulative distance of the candidate segment, it can be determined whether the shot boundary is included and the type of the boundary. The maximum distance can directly determine the location of the CTs, and the GTs are defined using inverted triangle pattern matching. Experiments on TRECVID 2007 test data and 100 dual-shots movie clips. Compared with the latest solution, the solution has an excellent accuracy and universally applicable for different types of video.

TL;DR: This paper improves upon the histogram and pixel difference based approach with fuzzy rule based approach and also gives a new approach which reduces the computation of framewise differences.
Abstract: In this paper we propose to summarize videos based on key frames. We improve upon the histogram and pixel difference based approach with fuzzy rule based approach and also give a new approach which reduces the computation of framewise differences. We test our methods using fidelity ratio and compression ratio on videos of sports from YouTube and UCF sports dataset, videos of commercials and sitcoms. The results of our methods are seen to be comparable to other state of the art approaches.

TL;DR: Experimental results support that the proposed technique works well with Snooker videos, providing a significant potential for automatic snooker video processing such as annotation, summarization and editing.
Abstract: Video content processing and analysis is going through a transition from low-level feature based techniques to high-level semantics based approaches. In this paper, we describe such a transition that low level features are processed to extract four semantic patterns, leading to high-level content analysis for snooker videos. Such extracted semantics and recognised patterns include: (i) full court scenes for snooker match, (ii) close-up view of snooker match; (iii) player's face, and (iv) audience's faces. Experimental results support that the proposed technique works well with snooker videos, providing a significant potential for automatic snooker video processing such as annotation, summarization and editing.

TL;DR: A separation theorem for convex fuzzy sets is proved without requiring that the fuzzy sets be disjoint.
Abstract: A fuzzy set is a class of objects with a continuum of grades of membership. Such a set is characterized by a membership (characteristic) function which assigns to each object a grade of membership ranging between zero and one. The notions of inclusion, union, intersection, complement, relation, convexity, etc., are extended to such sets, and various properties of these notions in the context of fuzzy sets are established. In particular, a separation theorem for convex fuzzy sets is proved without requiring that the fuzzy sets be disjoint.

TL;DR: This best-selling, easy to read book offers the most complete discussion on the theories and principles behind today's most advanced communications systems.
Abstract: This best-selling, easy to read book offers the most complete discussion on the theories and principles behind today's most advanced communications systems. Throughout, Haykin emphasizes the statistical underpinnings of communication theory in a complete and detailed manner. Readers are guided though topics ranging from pulse modulation and passband digital transmission to random processes and error-control coding. The fifth edition has also been revised to include an extensive treatment of digital communications.

TL;DR: In this article, a fuzzy logic is used to synthesize linguistic control protocol of a skilled operator for industrial plants, which has been applied to pilot scale plants as well as in practical situations.
Abstract: This paper describes an application of fuzzy logic in designing controllers for industrial plants. A fuzzy logic is used to synthesize linguistic control protocol of a skilled operator. The method has been applied to pilot scale plants as well as in practical situations. The merits of this method and its usefulness to control engineering are discussed. An avenue for further work in this area is described where the need is to go beyond a purely descriptive approach, and means for implementing a prescriptive or a self-organizing system are explored.

TL;DR: A twin-comparison approach has been developed to solve the problem of detecting transitions implemented by special effects, and a motion analysis algorithm is applied to determine whether an actual transition has occurred.
Abstract: Partitioning a video source into meaningful segments is an important step for video indexing. We present a comprehensive study of a partitioning system that detects segment boundaries. The system is based on a set of difference metrics and it measures the content changes between video frames. A twin-comparison approach has been developed to solve the problem of detecting transitions implemented by special effects. To eliminate the false interpretation of camera movements as transitions, a motion analysis algorithm is applied to determine whether an actual transition has occurred. A technique for determining the threshold for a difference metric and a multi-pass approach to improve the computation speed and accuracy have also been developed.
