Different kinds of features hold some distinct merits, making them complementary to each other. Inspired by this idea an index level multiple feature fusion scheme via similarity matrix pooling is proposed in this paper. We first compute the similarity matrix of each index, and then a novel scheme is used to pool on these similarity matrices for updating the original indices. Compared with the existing...
Social meetings provide important venues for people to get connected. However, it is challenging to explore reasons of social gathering, identify its key impact factors, and further use it to support people's social activities. In this paper, we present an embodied visual analytics system, which highlights analyzing and displaying social-cluster related information in real time. In the system, each...
The most perceptual Full Reference Image Quality Assessment metrics (FR-IQA) shared a common two-step model; local quality measurement, and pooling. In this letter, a novel pooling strategy based on harmonic mean is proposed to predict the final quality score in FR-IQA. In contrast to arithmetic mean, the harmonic mean tends to emphasize the contributions from the local severely distorted regions...
A new scheme is proposed to realize Unmanned Aerial Vehicle's (UAV's) automatic landing on the ship precisely in all weather, which is based on the infrared cooperative object on ship's runway and the infrared computer vision in UAV. Firstly the UAV is guided to the neighborhood of landing position by SINS, and then the seamless spiral search strategy is applied to acquire the accurate position of...
Mind Map is an effective graphic tool in expressing divergent thinking and has been widely applied in brainstorming, work plan, decision making and document drafting and so on. The modeling process of Mind Map is based on humans' subjectivity and lack of logical criterion support. On the other hand, it is expert in divergent thinking but weak in convergence, so it cannot meet the needs of divergence-convergence...
In the process of dealing with traffic accidents, the contour of the car body parts is very important to the information of the vehicle body. By using image processing techniques and methods, this paper proposed a new type recognition system of rear-view mirror outline. We also designed the way of active and passive vision measurement in the image acquisition phase; discussed the way of using the...
Electrostatic and van der Waals interactions are of central importance for many biological processes. Yet it is difficult to visualize and analyze the two interactions with existing graphical representations of proteins such as wireframe, VDW, and molecular surface due to the three-dimensional nature of protein interaction distribution. The molecular interaction field (MIF) is defined as a three-dimensional...
Program understanding plays an important role in the maintenance and reuse of open source code. Rapid evolving and bad documentation makes the understanding and reusing difficult. Design patterns are widely employed in the open source code. In this paper, we propose a design pattern directed clustering approach to help understand the structure of open source code. According to the approach, we have...
