Abstract: A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

Abstract: Methods and systems for detecting an object borderline. A first image with respect to the object can be captured by an image-capturing unit without a flash light and borderlines of the object can be detected. If the detection is successful, the detected borderlines can be outputted. Otherwise, a second image with respect to the object can be captured by the image-capturing unit by applying a flash light and the borderlines can be detected in the image. A geometric transformation between the two images can then be estimated. Finally, the border lines in the first image can be determined by transforming the borderlines detected in the second image. Such an approach effectively detects the appliance borderlines and avoids artifacts caused by applying flash.

Abstract: A processor controls a marking engine to print a uniform region having a visually uniform color for an observer within all areas of the uniform region. The processor also controls the marking engine to print different gloss patterns within the uniform region. The different gloss patterns have first and second gloss regions, and the gloss difference between the first and second gloss regions forms gloss marks. Additionally, the processor controls the marking engine to print different infrared patterns within the uniform region to form infrared marks. In some embodiments, the infrared patterns are only within the first gloss regions and are not within the second gloss regions.

Abstract: A method and apparatus for obtaining an image and providing one or more document files to a user is disclosed. The method may include receiving an image of a target object using an imaging device, analyzing the image to identify one or more features, and accessing a model database to identify an object model having features that match the identified features from the image. When the system determines that more than one model may be a match, the method looks for distinguishing features of the target object and selects a model that includes the distinguishing features. The method then includes, retrieving a document file that corresponds to the identified model from a file database, and providing the document file to a user.
