It uses visual attention model to segment image regions and eye-tracking technique to record fixations. Visual perception is obtained by analyzing the fixations in regions to measure gaze interests. Integrating visual perception into attention model is to detect the Regions Of Interest (ROIs), whose features are extracted and analyzed, then feedback interests to optimize the results and construct user profiles.展开更多

The principal point is assumed to locate at the image center with zero skew and the same aspect ratio, and the interior parameters are fixed, so the self-calibration becomes focal-length cali- bration. Existing focal length calibration methods are direct solutions of a quadric composed of fundamental matrix, which are sensitive to noise. A quaternion-based linear iterative Least-Square Method is proposed in this paper, and one-dimensional searching for optimal focal length in a constrained region instead of solving optimization problems with inequality constraints is applied to simplify the computation complexity, then unique rotational matrix and translate vector are recovered. Experiments with simulation data and real images are given to verify the algorithm.展开更多

A method is proposed to categorize different places in a typical indoor environment by using a Kinect sensors for mobile robot exploration. At first, the invariant feature based images stitching approach is adopted to form a panoramic image according to Kinect visual information, and the translation between Kinect depth information and obstacle distance information is performed to obtain virtual LIDAR data. Then, the semantic classifier is designed by using convolutional neural networks (CNN) for indoor place eategorization based on Kinect visual observations with panoramic view. At last, a frontier-based exploration method is applied to carry out indoor autonomous exploration of mo- bile robots, which integrates the CNN-based categorization approach. The proposed method has been implemented and tested on a real robot, and experiment results demonstrate the approach effective- ness on solving the semantic categorization problem for mobile robot exploration.展开更多

Literature and psychology has been linked together starting from Plato and Aristotle period. In the neuropsychological domain, synaesthesia allows people to combine several perceptions together; while in literature, it magically melts the “voice” of the author’s into the works. To interpret the female voice of the book, this article analyzes the voice of poverty and distress, of pursuing ethnic equality, and of pursuing female independence, on the basis of the psychological perception, synaesthesia, so as to reveal Sandra Cisneros’s feminist voice on the reflections of ethnic Mexican female values by her beautiful naive poetic language, with a pure and innocent tone.展开更多

I will stress that these diverse conceptions are mainly formulated in the context of Poincar6's controversies in opposition to logicism, to formalism, and in the context of Poincar6's very peculiar conventionalism. I will try to demonstrate that, in each case, Poincar~ comes close to a specific tradition (Kant, of course, but also Leibniz and Peirce).展开更多

Richard Aldington's two poems, London (May 1915) and Eros andPsyche, come to depict Surrealist image spheres, as their visual representations in words would show. The dialectical optic of the poet comes to reveal an allegorical synthesis, giving birth to new meanings. The city of London shows the irrational fusion of the opposites, in a way which a Surrealist reading of these two poems is able to construct a critical virtue.展开更多

In the interaction design, establishment of metaphor interactive model is relates the key of user image model and designer image model is, through finding in two models product altogether has the characteristics, and reveals with the design language the characteristics, communicates with the user, thus enables the user to understand and grasp product the structure, function, usage-style and other information of rapidly. The inheritance rise of culture to some altitude, with the life or death strong and weak dependence department of the nationality and French structuralism anthropology believes that the behavior and standard of humanity are, the origins and development processes of various cultures by the deep structure of culture is decided has its similarity. Under this basis, this paper proposes the new combination model for later integration that will promote the development of the contemporary art design.展开更多

His too-liminal status as the last Victorian novelist, regional writer, and a collector of English rustics, has been vivaciously debated and contested (Miller, 1970; Widdowson, 1989; Moore, 1990; Morgan, 1992; Armstrong, 2000; Mallet, 2002; Nemesvari, 2011). This argument contributes to the debate on the relation between the real and the textual in Hardy's last novel, Jude the Obscure (1895), which shows that Hardy's language has features of a self-referential novel, close to the antimimetic poetics of postmodernist genres, which insists, however, on the connection with the real, where lies the inspiration for creativity and political intervention. Through the analysis of the allegorical figures of "intertexts" interwoven in the language of the novel, it will be argued that the representation of the novel registers the connection between Hardy's visual imagination and his intention to intervene in a discursive field.展开更多

The system is composed of a machine vision device, a delta robot and a linear stage, and the concerned hardware, software and working methods were developed completely and verified successfully. During the phase of machine vision, the image of object was captured by camera, and then the process of smoothing filter, threshold algorithm and edge detection, was applied so as to obtain the edges of image. Finally, DV-GHT (Displacement Vector Generalized Hough Transformation) algorithm was used to recognize the center of multiple and arbitrary 2-D shapes objects. After the center of objects was recognized, the objects were delivered to the workspace of a delta robot by a motorized stage. Through the coordinate transformation between the camera and the robot system, the information of center can be converted to control commands for every working motors. Following, the delta robot picks up objects to the specified position sequentially by the trajectory planning and tracking controls. The software of C++/CLI is used to achieve the phase of motion controls and the program of DV-GHT is used to detect and conduct the positions for four different characteristics of the objects simultaneously so as to indicate the delta robot to classify the objects successfully.展开更多
