Software Defined Networking (SDN) has been a prevalent networking paradigm in recent years. Due to its simplicity to quickly deploy and fully manage networks, both academia and industry are interested in this technology. Nevertheless, there are still many issues to be solved. In this pape r, we propose to divide flow table into two separate tables, namely path table and traffic table, to minimize...
Digital cameras that gradually replace conventional cameras store photographs in digital format. As a result, captured images can be more easily processed. Consequently the quality of image is more important. In this paper, we present an overview of image quality attributes of different contrast enhancement in gray level images. Moreover, we present results of analysis for some contrast enhancement...
Studies of contrast sensitivity of the human eyes show that logarithmic curves obey the Weber-Fechner law of just noticeable difference response in human perception. In this paper, we propose a local contrast enhancement algorithm with logarithm-based curves for both high dynamic and low dynamic images and this algorithm can adaptively change the curvature with local information. We also define two...
