Playing a vital role, saliency has been widely applied for various image analysis tasks, such as content-aware image retargeting, image retrieval and object detection. It is generally accepted that saliency detection can benefit from the integration of multiple visual features. However, most of the existing literatures fuse multiple features at saliency map level without considering cross-feature...
Local oriented statistical information booster (LOSIB) is a descriptor enhancer based on the extraction of the gray level differences along several orientations. Specifically, the mean of the differences along particular orientations is considered. In this paper we have carried out some experiments using several classical texture descriptors to show that classification results are better when they...
In order to realize texture image segmentation, a new texture segmentation method is presented. The method fused with Local Binary Pattern (LBP), Gray-level Co-occurrence Matrix (GLCM) and permutation entropy. After processing the texture image by the rotation invariant LBP operator, the LBP image can be obtained. Then co-occurrence matrixes can be calculated in the LBP image, some features which...
In this article, the database of sEMG corresponding to the six gestures with two,four and eight channels is collected and established through increasing the number of surface electrode muscle telecommunication reasonably.Two-channel method used in the previous studies in laboratory is improved to make the method suitable for four-channel and eight-channel.On this basis ,the activity of sEMG is detected,the...
With recent advances in radio-frequency identification (RFID), wireless sensor networks, and Web services, physical things are becoming an integral part of the emerging ubiquitous Web. Correlation discovery for ubiquitous things is critical for many important applications such as things search, recommendation, annotation, classification, clustering, composition, and management. In this paper, we propose...
The technology of panoramic image construction is widely used in many conditions. As the increasingly demand of monitoring system application, the attribute of real-time is more important during the panoramic construction. This paper describes a method of fast building panoramic video and output frames in real-time. SURF algorithm is employed to extract features and a new method is developed to eliminate...
This paper describes a pedestrian detection method using feature selection based on logistic regression analysis. As the parent features, Haar-like and Histograms of Oriented Gradients (HOG) features are used manually. For the statistical analysis, stepwise forward selection, backward elimination, and Least Absolute Shrinkage and Selection Operator (LASSO) methods are applied to our Logistic Regression...
Local Binary Pattern (LBP) has been well recognised and widely used in various texture analysis applications of computer vision and image processing. It integrates properties of texture structural and statistical texture analysis. LBP is invariant to monotonic gray-scale variations and has also extensions to rotation invariant texture analysis. In recent years, various improvements have been achieved...
The character thinning can greatly eliminate redundant information and improve the speed and accuracy of the character feature extraction. The paper proposes an algorithm for extracting characters' central skeleton directly, which is based on the length of eight-direction and the line connected by inscribed circle center of the character segment, while the information of strokes is obtained. The experimental...
Automatic Fingerprint Recognition Systems (AFRSs) rely on minutiae position and orientation within the fingerprint image for matching. Minutiae information is highly accurate provided that the fingerprint image matched is of high quality. However, this is not always the case because of diseases and hash working conditions that affect fingerprints. In order to maintain high level of security independent...
The acts to submit the copied programs of other person make problems in the subject of the programming exercise in university curriculum. Teachers could not make accurate scores and evaluate the reached learning level of students. The code clone detection technique is to automatically detect the copied programs. Researches of the code clone detection technique have been proposed. The object of these...
People in a color image, particularly facial patterns are important and interesting visual object. Thus, color reproduction for skin tone becomes the foremost treatment, because skin color is a key memory color in color application systems. Previous studies suggested skin color reproduction by mapping only to the center value of preferred skin region. However, it is not suitable to determine one preference...
This paper presents an approach to the Chinese Personal Name Disambiguation (PND). The key to clustering is the similarity measure of context, which depends on the features selection and representation and calculation method. First HIT Tongyici Cilin (Extended) is introduced to Chinese PND to enhance the clustering effect. Exploration about more word similarity is also performed to alleviate the data...
A novel method of registering the satellite images is introduced in this paper. The existing vector road maps are used as control information instead of the ground control points. The whole process is divided into 4 issues: find the initial relationship between the road maps and the satellite image with the help of the initial rough value of RPCs (the Rational Polynomial Coefficients);find the corresponding...
Facial expression recognition by artificial intelligence has become a hotspot and produced promising results in recent years. However, most recent work focuses on posed expressions whose involved muscles and dynamics are different from those of spontaneous ones. So this paper proposed a novel two-layer approach, combining dynamic head motion features with static appearance features, to recognize spontaneous...
As rotating machines perform an important role in industrial applications, many researchers have developed various condition monitoring system and fault diagnosis system by applying various techniques such as signal processing and pattern recognition. Recently, fault diagnosis systems using artificial neural network have been proposed. This paper proposes the neural-network-based fault diagnosis system...
An improved fuzzy edge detection algorithm is presented, and the drawbacks of Pal fuzzy algorithm have been overcome by a new enhancement operator based on gauss function. Firstly, the threshold parameter was confirmed by maximum variance automatic selection threshold method, and then linear translation was used to define a new membership function based on the new threshold parameter. As a result,...
This paper study a PDE variational model to image denoising and restoration. The existence and uniqueness of the solution is discussed. A new model of image denoising and restoration is deduced by gradient descent flow method. Then, A new numerical analysis model is obtained. The model can preserve the edge feature and smooth the image. The numerical experiments show that the model delivers better...
We have investigated a technique for recognising faces invariant of facial expressions. We apply multi-linear tensor algebra, which subsumes linear algebra, to analyse and recognise 3D face surfaces. This potent framework possesses a remarkable ability to deal with the shortcomings of principle component analysis in less constrained situations. A set of vector spaces can be used to represent the variation...
The useless samplings and accumulations of randomized Hough Transform (RHT) are largely reduced with the help of the ellipse's conic control point constraint and the constraint of the normals at the endpoints of a chord. The fuzzy confidence based on vision perceptual grouping is used to further eliminate false candidate ellipses introduced by the same distorted ellipse. The experimental results show...
