2013/7/24
General object recognition and image understanding is recognized as a dramatic goal for computervision and multimedia retrieval. In spite of the great e®orts devoted in the last two decades, it s...
PKU-NEC TRECVid 2011 SED: Sequence-Based Event Detection in Surveillance Video
PKU-NEC Sequence-Based Surveillance Video
2013/7/24
In this paper, we describe our system for surveillance event detection task in TRECVid 2011. We focus on pair-wise events (e.g., PeopleMeet, PeopleSplitUp, Embrace) that need to explore the relationsh...
Visual Saliency Detection by Spatially Weighted Dissimilarity
Visual Saliency Detection Spatially Weighted Dissimilarity
2013/7/24
In this paper, a new visual saliency detection method is proposed based on the spatially weighted dissimilarity. We measured the saliency by integrating three elements as follows: the dissimilarities ...
Detection and Location of Near-Duplicate Video Sub-Clips by Finding Dense Subgraphs
Near-duplicate video detection Sub-clip location Graph shift
2013/7/24
Robust and fast near-duplicate video detection is an important task with many potential applications. Most existing systems focus on the comparison between full copy videos or partial nearduplicate vi...
In this paper, we proposed a fast and robust unsupervised framework for anomaly detection and localization in crowed scenes. Our method avoids modeling the normal state of the crowds which is a very c...
Adaptive Moving Cast Shadow Detection
Shadow Detection Ratio Edge Ratio Brightness Video Surveillance.
2013/7/24
Moving object detection is an important task in real-time video surveillance. However, in real scenario, moving cast shadows associated with moving objects may also be detected, making moving cast s...
Coarse-to-Fine Dissolve Detection based on Image Quality Assessment
dissolve detection coarse-to-fine image quality assessment dissolve length normalization shot boundary detection
2013/7/24
Although many approaches have been proposed for video shot boundary detection, dissolve detection remains an open issue. For a dissolve, we could find that the video frames reveal a “clarity–blur–cl...
A Rotation Invariant Descriptor for Robust Video Copy Detection
