I have over 8 years of development and implementation experiences over 180+ apps from small applications to large scale & complex enterprise solutions . 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. ===== Strong Skills ===== + Android SDK, Android 2.3 - 7.0 Development + iOS SDK, iOS Development(iPhone & iPad) + PHP, Laravel, CodeIgnitor,Zend, WordPress, Zoomla + Databases: MySQL, MS SQLServer, SQLite, MongoDB + Augmented, OpenCV, OpenTok, Optical Character Recognition + XMPP (Ejabberd, Openfire, MongooseIM). + WebRTC, Websocket, SocketIO + JavaScript, jQuery, AngularJS + Html, CSS, Twitter Bootstrap, LESS, Gulp + Cloud Platform: AWS and Azure + Payment Gateway: Paypal, Stripe, Braintree

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.
