This paper proposed a novel blind image quality assessment method that is created by training a convolutional neural network to learn discriminant features of image quality and fitting the features with a support vector regression to get an evaluation score. The pooling procedure is help to reduce the feature dimension and improve computation efficiency. The proposed method does not need any hand-crafted...
This paper on the. Net platform three layer architecture of online bookstore system design process were research and exploration, and the second layer architecture comparison of advantages and disadvantages. Three layer architecture thought take the strategy of "divide and conquer", the separation of system design key points of each to a separate layer implementation, and through mutual...
Deep learning is a multilayer neural network learning algorithm which emerged in recent years. It has brought a new wave to machine learning, and making artificial intelligence and human-computer interaction advance with big strides. We applied deep learning to handwritten character recognition, and explored the two mainstream algorithm of deep learning: the Convolutional Neural Network (CNN) and...
Since the apoptosis protein plays an important role in understanding the mechanism of programmed cell death, so further to reveal the mechanism of subclass for apoptosis can bring more insights to their function. Here, our group established a dataset included 239 anti-apoptosis proteins and 222 pro-apoptosis proteins in our previous work. The extraction of information based on sequence information,...
Visual saliency is an important cue in human visual system, it can identify salient region in image. Image contrast has been utilized as an effective feature to detect the salient region. The conventional contrast measures utilize both spectral and spatial properties of image in many salient region detection methods. However, they only consider the local characteristics of image region, consequently,...
In this work, an efficient data storage method of NoSQL database is proposed for mobile devices and Internet applications to monitor appliance status in a home environment in real-time, and a home energy management (HEM) mobile App for monitoring this information is also developed. An HBase cluster is constructed as a test bed for evaluation. The evaluation is conducted based on the developed APP...
Localization is the enabling technology of geolocation database assisted Cognitive Radio Networks (CRN) in TV White Space (TVWS), as the location is required in the implementation of geolocation database approach by regulators such as FCC and Ofcom. This paper proposes a novel Sensing enAbled Localization and Tracking (SALT) system, which locates Secondary Users (SUs) and tracks their movements. In...
In this paper, we present a boosting approach by combining the pose estimation and the upper body tracking to on-line recognize human actions. Instead of using a predefined pose to initialize the human skeleton, we construct a key poses database with depth HOG features as searching indexes. When user enters the camera view, we automatically search the database to get the initial skeleton. Then we...
HTML5 is a great development of Web standard in nearly more than 10 years. It provides a powerful support for RIA(Applications of Rich Internet).Based on a comparison with other rich client technologies, a rich client Web architecture based on HTML5 is proposed. The paper emphatically analyzed the theory and technology of the client control in the architecture. The experiment proves that the structure...
Tennis Real Play (TRP) is an interactive tennis game system constructed with models extracted from videos of real matches. The key techniques proposed for TRP include player modeling and video-based player/court rendering. For player model creation, we propose the process for database normalization and the behavioral transition model of tennis players, which might be a good alternative for motion...
This paper presents a novel algorithm for vascular tree segmentation based on shortest path connection. The connected vascular tree provides topological features that are instrumental in image-aided diagnosis. The proposed method can enforce the connectivity as well as remove the false detection at same time. Multi-scale ridge detector is employed that can locate vessels with different widths. To...
In the paper a Chinese remainder theorem based new bio-cryptography scheme is proposed, which is designed in cascade structure and adopts an error correction technique to improve the performance, to tackle the problems in secret sharing based methods. In key retrieval, it greatly brings down the number of operations, avoids exhaustive calculation of tarsus, reduces the computation and improves the...
Tennis Real Play (TRP) is an interactive tennis game system constructed with models extracted from real game videos. The key techniques proposed for TRP include player modeling and video-based player/court rendering. Experiments show that vivid rendering results can be generated.
Image-based rendering has been highly developed for its wide applications such as view synthesis and special effects in movies. In this paper, we proposed a tennis player rendering system synthesizing diverse player action/motion based on extracted database from broadcasting game videos. The system gathers database by retrieving the player from videos and synthesizes various kinds of player action/motion...
A data warehouse is built as a layer on top of existing operational database systems. Once built, it has to be regularly updated (refreshed). Currently, most data warehouse approaches employ static refresh mechanisms whereby updates are based on a static timestamp, eg. once every day/week/quarter only. Whilst for some systems this might be adequate, others require a more rigorous approach ensuring...
The important factors for the development of GPS navigation system are the speed and cost of electronic map display with the mass data. It is essential to improve the speed of the electronic map information retrieval and browsing without increasing the cost. This paper presents a novel superfast image data retrieval method based on Hash function. This method simplifies the complexity of traditional...
In this paper, we present a novel data structure representing the environment with occupancy grid cells while each grid map is associated with a set of line features extracted from laser scan points. Due to the fact that line segments are principal elements of artificial environments, they provide considerable geometric information about the environment which can be used for enhancing the accuracy...
The topic correlation judgment algorithm based on weight and threshold is proposed as for the problem that Web pages which are closely related to the given topic may be neglected due to not all keywords given by the users in the pages when users retrieve the topic they desire on the Internet. The algorithm retrieves the topic on the Web sites in depth by the hierarchical key structure on the basis...
This paper presents a method based on information entropy to analyze the capacity of covert channels. Built upon noninterference, the method is firstly used to calculate the covert channel capacity, then to analyze the factors that have an impact on this quantity. Finally an example is given of the capacity calculation for covert channels in a multilevel secure database.
