Abstract: The display of images comprising animated microstructures can be used to create beautiful information and publicity sites attracting the attention of clients. Especially for clients visiting Web sites, images with animated microstructures are capable of forwarding a message incorporated into the animated microstructure (e.g. an advertisement). The present invention discloses a method for creating, respectively, displaying a target image with an animated microstructure, where the target image is made of a succession of target image instances which differ from each other by an embedded microstructure which evolves over time. An animated microstructure image requires the definition of an original image, an embedded microstructure, a transformation describing how the microstructure evolves over successive image instances, possibly a warping transformation mapping the target image space into the animated microstructure and possibly a set of basic colors for rendering target image instances.

Abstract: A method of generating an image incorporating a microstructure includes the steps of obtaining an original image, generating a microstructure, and rendering a region or the whole said original image with said microstructure. The operation of generating the microstructure includes an automatic synthesis of microstructure elements from original microstructure shapes.

Abstract: Due to the wide availability of photocopiers, scanners and printers, security documents are more and more subject to counterfeiting attempts. The present disclosure describes security documents incorporating a new security feature based on a microstructure, whose shapes vary according to intensity and color, as well as methods and computing systems for synthesizing such security documents. The microstructure may be composed of text, graphic elements and symbols. Since the security document is built on top of the microstructure, document elements such as text, graphics and images as well as microstructure elements cannot be erased or modified without introducing visible discontinuities in the security document. Furthermore, thanks to transformations having the effect of warping the microstructure into different orientations and sizes across the security document, individual microstructure elements cannot be simply copied and inserted elsewhere.
