With the emergence of ubiquitous computing, a dedicated network enabling applications for such systems becomes increasingly indispensable. Given the typical user-centered focus of ubiquitous applications, the dedicated network should be able to reconfigure itself autonomously according to the current context of use. In this paper, a new definition of a cognitive network is given and a clear line is...
In this paper, a novel image quality assessment, called Structure Analysis Image Quality Measurement (SAIM), is proposed by evaluating the difference of the distorted image from the reference image on three aspects: the average luminance, edge intensity and orientation. It is sensitive to edge change, which consists well with the perceptual characteristics of human vision. The experiment results demonstrate...
In the present study, we investigated the effect of ERK1/2 and JNK signaling pathway in the inhibition of AcSDKP on the proliferation and collagen synthesis in cultured rat cardiac fibroblasts induced by PDGF. By using MTT assay and Western Blot analysis, we found that treating the fibroblasts with PDGF, phospho-ERK1/2 and phospho-JNK expression was significantly increased compared with the control...
Influenced by global financial crisis and expanding enrolment of higher education, college students face serious employment and re-employment situation. College students must own core competence if they want to get success in employment competition. The professional training model adapting to market needs is to develop comprehensive professionals with advantages in creation, which can be achieved...
Under the assumption that the image information is determined mostly by the scene illumination and the objects structure, a new clutter metric, named the relative target complexity based clutter metric, for human visual systems is presented in this paper. The average intensity and the target complexity, independent of each other, are used to represent the image signal in the new metric. And its promise...
A method to quantify clutter in color images is presented. This method is based on a grayscale clutter metric, target structure similarity (TSSIM) metric, which showed the best correlation with human perception than the other available metrics. The proposed new metric is designed to measure the background clutter in the perceptually decorrelated quasi-uniform color space of CIELAB. The TSSIM metric...
Optical coherence tomography (OCT) is a rapidly emerging imaging modality that can non-invasively provide cross-sectional, high-resolution images of tissue morphology in situ and in real-time. Previous studies have demonstrated that OCT is capable of accurately visualizing the pathological changes in the living kidney in vivo using the Munich-Wistar rat model. In this work, we establish, for the first...
