Abstract
This project was designed according to the creative ideas in Daily Prophet (the newspaper in the science fiction Harry Potter), and it also realized a kind of software with similar science-fiction effect in the novel. The software can recognize the scene in camera, analyze the image in the camera according to certain algorithm, and achieve the dynamic information corresponding to the picture by interacting with the server. It can display in the client side, ‘replacing’ the static information with dynamic information, so that the dynamic information can ‘blend into reality’ and enhance the visual experience. Relying on all kinds of mobile terminals, this project can be widely applied in print media, museum, education, commerce, etc. aiming to improve the amount of information carried by the static pictures greatly, enrich the forms of expressions for images and strengthen the dynamic visual experience. This project analyzes the problems in image matching, approximate retrieval, image tracking and load bearing of the mobile platform. An assorted algorithm has been designed and developed independently for processing the images and videos, so that the algorithm can satisfy the demands of the algorithm to the greatest extent and achieve the expected effect.
