To blindly evaluate the visual quality of image is of great importance in many image processing and computer vision applications. In this paper, we develop a novel training-free no-reference (NR) quality metric (QM) based on a unified brain theory, namely, free energy principle. The free energy principle tells that there always exists a difference between an input true visual signal and its processed...
Blur plays an key part in evaluating of camera image quality. It leads to decrease of high frequency information and accordingly changes the image energy. Recent researches in quaternion singular value decomposition show that the quaternion's singular values and associated vectors can capture the distortion of color images, and thus singular values can be utilized to assess the sharpness of camera...
A method based on time-domain Baum-Liu-Tesche (BLT) equations of transmission line model is presented in this paper for solving the crosstalk problem between a single wire and a twisted-wire pair. The single wire and the twisted-wire pair (TWP) together are modeled as a set of uniform multi-conductor transmission lines with abrupt interchanges of wire positions at the end of each loop of the twisted-wire...
Enterprise strategy that changes with the environment is related to the survival of enterprises and has attracted the attention of academic. Many scholars studied them from different angles, but few study the evolution of strategic theories from the enterprise environment angle. Therefore, this paper tried to review the development course of enterprise strategy theory based on basic definition enterprise...
Only if the enterprise adheres to customer-oriented in the product design and provides the value beyond rival and strives for customers and maintaining customers, then it will acquire sustained competitive advantage. Then, the author described the characteristics of enterprise core competence and customer value based on the detailed descriptive. Finally, the paper analyzed the inner relations of customer...
