Microstructure Imaging is an image synthesizing technique for creating images
incorporating a freely created artistic or text microstructure.
When seen from a certain distance, mainly the global image is visible.
When seen from nearby, mainly the microstructure is visible.
With microstructure imaging, the dots composing the image are
microstructure patterns whose thickness is tuned according to the local
image intensity. This generates very characteristic images which are hard
to copy and provide two layers of information, the global image
layer and the microstructure layer. |
With an input grayscale or color image and a microstructure specified by a bitmap, microstructure imaging automatically synthesizes the target microstructure image. Thus, individualized security documents may be generated.
The image of the African warrior is composed of a microstructure representing the African symbols shown below.
Artistic screening is a first generation image reproduction technique
incorporating freely created artistic screen element shapes for generating
halftones. Artistic screening enables the shape of screen dots to be
tuned according to the artists intention. By creating artistic screens which
may take any desired shape, screening effect, which up to now were considered
to be undesirable, are tuned to convey additional information for artistic
purposes. Furthermore, screen elements may undergo smooth transformation in
order to produce special effects.
