Abstract:
In the present digital world, digital images and videos are the main carrier of information. However, these sources of information can be easily tampered by using readily available software thus making authenticity and integrity of the digital images an important issue of concern. And in most of the cases copy- move image forgery is used to tamper the digital images. Therefore, as a solution to the aforementioned problem we are going to propose a unique method for copy-move forgery detection which can sustained various pre-processing attacks using a combination of Dyadic Wavelet Transform (DyWT) and Scale Invariant Feature Transform (SIFT). In this process first DyWT is applied on a given image to decompose it into four parts LL, LH, HL, and HH. Since LL part contains most of the information, we intended to apply SIFT on LL part only to extract the key features and find a descriptor vector of these key features and then find similarities between various descriptors vector to conclude that there has been some copy-move tampering done to the given image. And by using DyWT with SIFT we are able to extract more numbers of key points that are matched and thus able to detect copy-move forgery more efficiently.

Abstract:
Finite element analysis can research the change of the structure and the interior field intensity of human and animal body organs and tissues through simulation experiment. We use finite element analysis software to analyze the spinal cord surface potential and research the transmission feature of signals generated by interneurons in spinal cord which are related with body motion control and sensory processing. A three dimensional model of electrical source in rat's spinal cord was built, the influence on potential distribution on spinal cord surface caused by position changes of electrical source in transverse direction and dorsoventral direction was analyzed and calculated. We obtained the potential distribution curves of spinal cord surface and compared the results with data from animal experiments, verifying the feasibility of scheme of locating the excitatory through potential distribution on spinal cord surface.

Abstract:
The development and professionalization of a video game requires tools for analyzing the practice of the players and teams, their tactics and strategies. These games are very popular and by nature numerical, they provide many tracks that we analyzed in terms of team play. We studied Defense of the Ancients (DotA), a Multiplayer Online Battle Arena (MOBA), where two teams battle in a game very similar to rugby or American football. Through topological measures - area of polygon described by the players, inertia, diameter, distance to the base - that are independent of the exact nature of the game, we show that the outcome of the match can be relevantly predicted. Mining e-sport's tracks is opening interest in further application of these tools for analyzing real time sport
