Image processing algorithms nowadays are very popular area of research. This is the area that gives hide possibilities to discover new algorithms and ways of optimization. What is more, it is very important subject in medicine, real time application and normal life, areas, where everyday people use more and more computer vision technology and artificial intelligence.

The biggest problem of image processing algorithms is them complexity and image limitations. Some of them are more universal and some needs very specific and precise input image.

The main aid of this diploma project is to create an application for Euro banknote recognition with new algorithms developed and created by the author and other popular and well-known methods. The project shows that it is possible to implement sophisticated, greedy algorithms on mobile phone, with few memory and weak CPU and make complex tasks with simple tools and methods. The program is universal and does not need precised input image, in this way everybody with Android mobile phone or personal computer can try it.

The idea of application is simple: the user make a photo of Euro banknote. Banknote can be rotated, but it has to be on the plain background. The application analyses the image step-by-step, showing every step of algorithm, or directly returning the result of recognition.
