I have over 8 years of development and implementation experiences over 180+ apps from small applications to large scale & complex enterprise solutions . My goal is to 130% fulfill the expectations of my clients – the extra 30% being the anticipation of problems or adding ideas that my clients may not have realized. You will find me easy to communicate with to an extent by which you may be surprised, but that is because I believe only a dedicated connection with my employer can lead to truly extraordinary creations. I don't know "impossibility" during development. Services: * Daily or weekly updates during development * Deliver clean and robust code, upload on app store after development * Maintenance and any updates free after development

Image tampering detection based on stationary distribution of Markov chain

With the development of image editing software such as Adobe Photoshop, digital image can easily be manipulated and hardly detected by human eyes. If we take this issue for granted, it may eventually be harmful for our digital world, especially for the credibility of news coverage. Many researchers have worked on image forensics and a number of image tampering detection techniques have been proposed in recent years.
