Attention Driven Face Recognition: A Combination of Spatial Variant Fixations and Glance
Face Recognition Human Visual System
2011/7/24
This paper proposes a novel face recognitionalgorithm inspired by the selective attention of Human VisualSystem (HVS). We record four observers’ eye movements whenthey are viewing 100 FRGC [1] frontal...
Probe the Potts States in the Minicolumn Dynamics
minicolumn Potts states intrinsically-busting neuron.
2011/7/24
Minicolumn has been widely accepted not only as the basic structural element of the cortex anatomically, but also as the fundamental functional unit physiologically. And, it is believed by many theori...
WHEN CODEWORD FREQUENCY MEETS GEOGRAPHICAL LOCATION

2011/7/24
When codeword frequency meets geographical location inlandmark search applications, is it still discriminative forthe search procedure? In this paper, we give a systematicinvestigation about how geogr...
Visual Saliency Detection by Spatially Weighted Dissimilarity
Visual Saliency Detection Spatially Weighted Dissimilarity
2011/7/24
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 ...
A Unified Framework for Locating and Recognizing Human Actions
Unified Framework Locating Recognizing Human Actions
2011/7/24
In this paper, we present a pose based approach for locating and recognizing human actions in videos. In our method, human poses are detected and represented based on deformable part model. To our kn...
Human saccade is a dynamic process of information pursuit. Based on the principle of information maximization,we propose a computational model to simulate human saccadic scanpaths on natural images. T...
Computing Importance of 2D Contour Parts by Reconstructability
Computing Importance 2D Reconstructability
2011/7/24
Part-based representation has become an essential representation for objects. Different parts of a shape havevarious importance to shape perception. Concerned bythe contributions of local parts to the...
Advanced Spatial and Temporal Direct Mode for B Picture Coding
Advanced Spatial Temporal Direct Mode
2011/7/24
The direct mode in H.264/AVC can efficiently improve the coding performance of B pictures, since it exploits the spatial or temporal correlation by deriving its motion vector from previously encoded i...
Mode-Dependent Intra Frame Interpolation for H.264/AVC Compressed Video
Mode-Dependent Intra Frame Interpolation
2011/7/24
In this paper, a mode-dependent intra frame interpolation method is proposed for H.264/AVC compressed video. The intra prediction mode information is taken into account in the interpolation filter des...
Detection and Location of Near-Duplicate Video Sub-Clips by Finding Dense Subgraphs
Near-duplicate video detection Sub-clip location Graph shift
2011/7/24
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...
A Parallel Context Model for Level Information in CABAC
CABAC Parallel Context Mode Level Information
2011/7/24
Context-adaptive binary arithmetic coding (CABAC) is one of the most time-consuming modules in H.264/AVC decoder. A potential way to accelerate CABAC is by parallelization. However, the context modeli...

Action recognition Spatial-temporal local feature Local feature group Discriminate group distance Mahalanobis distance
2011/7/24
Although the spatial-temporal local features and the bag of visual words model (BoW) have achieved a great success and a wide adoption in action classification, there still remain some problems. Fir...
Adaptive Moving Cast Shadow Detection
Shadow Detection Ratio Edge Ratio Brightness Video Surveillance.
2011/7/24
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
