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.

01 Jan 2004TL;DR: The dynamic information present over different frames of a sports video is exploited to characterize the change in the configuration of players across different frames to characterize the scene dynamics.
Abstract: Dynamic changes of object positions provide an important clue for video characterization. In the present work, we exploit the dynamic information present over different frames of a sports video to characterize the change in the configuration of players across different frames. For scene dynamic characterization firstly location of players are detected by using motion based segmentation. We then construct a polygon with the players placed at the vertices of the polygon. Next the change in the shape of the polygon across different frames is computed in terms of the difference in the moments of the polygon shape. The difference is computed for seven moment invariants. The mean of these difference values, called mean-difference, is used as the key feature for characterizing the scene dynamics. An evolutionary learning based fuzzy rule based system is developed for characterizing sports sequences using duifference values.

TL;DR: This paper presents a method based on Edge histogram descriptor to accelerate shot cut detector algorithm for real-time applications using a Field Programmable Gate Array integrated architecture to accelerate this treatment.
Abstract: This paper presents a method based on Edge histogram descriptor to accelerate shot cut detector algorithm for real-time applications. In fact, before any content-based manipulations, the hierarchical structure of video must be determined and software pure solution is not suitable for this application due of constraints imposed by this algorithm. In this context we have used a Field Programmable Gate Array (FPGA) integrated architecture to accelerate this treatment.

TL;DR: Experimental results support that the proposed hybrid scheme to combine some features and techniques for detecting all sorts of shot cuts inside general videos outperforms the benchmark in terms of the precision-recall rates.
Abstract: Video temporal segmentation is normally the first and important step for content-based video applications. Although existing research on shot cut detection is active and extensive, it still remains a challenge to achieve accurate detection of all types of shot boundaries. In this paper, we propose a hybrid scheme to combine some features and techniques for detecting all sorts of shot cuts inside general videos. The hybrid scheme contains two processing modes, which are unified by a mode-selector to decide which mode the scheme should work on in order to achieve accurate temporal video segmentation. Via using the publicly test data set from Carleton University, we report extensive experimental results to evaluate the proposed algorithm. In comparison with existing algorithms, the experimental results support that the proposed algorithm outperforms the benchmark in terms of the precision-recall rates in detecting all types of shot cuts.

TL;DR: This technique uses a combination of low-level features and high-level rules which organizes the video into scenes, shots and key-frames, and a likelihood function is designed for improving the accuracy of scene boundary results.
Abstract: In this paper, we present a technique for semantic video segmentation. Our technique uses a combination of low-level features and high-level rules which organizes the video into scenes, shots and key-frames. Features in color domain is calculated and utilized for detecting the key-frames and estimating the similarity between shots. By applying a set of high-level rules, similar shots are merged and the scene boundaries are determined. Finally, a likelihood function is designed for improving the accuracy of scene boundary results. Experimental results from several Hollywood movies have demonstrated and show a better performance of both precision and recall has been achieved comparing with other existing works.

TL;DR: This work proposes a novel and very simple approach for Shot Boundary Detection (SBD) that has lesser complexity compared to existing methods and uses a technique called Computed Tomography for SBD.
Abstract: Videos are large volume objects. They are used for variety of applications in our day-to-day life. Manual operations on video are inconvenient. Hence an automatic system is required to analyse the video content. The first and most important step in any video processing application is shot boundary detection. We propose a novel and very simple approach for Shot Boundary Detection (SBD). This work has lesser complexity compared to existing methods. We use a technique called Computed Tomography for SBD. The method can be applied to any type of videos such as home, surveillance, sports or entertainment videos. The result of our work shows the excellence of the technique in SBD.

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: 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.
