摘要： A fast text/graphics resolution improvement algorithm is based on boundary parameterization and uses chain-code table look-up. Given an input representation containing text/graphics objects, the boundary of each object is traced, parameterized, smoothed, and subsequently rendered. Instructions for the critical operations are stored in one or more pre-computed look-up tables (LUTs) which is/are accessed during on-line operation, resulting in an algorithm that is fast and computationally inexpensive with low memory requirements. A very flexible framework is presented which can be utilized in a variety of applications requiring resolution improvement.

摘要： Disclosed are embodiments of systems and methods for identifying features using color information in an image. The image may be formed from one or more display images comprising color information and features or feature components. Because color information may be used to identify features, more than one feature or feature component may be displayed in a display image. Because a plurality of features may be identified in a calibration image, an image system, such as a projector-camera system, can reduce the number of display images needed to calibrate the system.

摘要： Smart printing/copying techniques for controlling the printing/copying and editing of a document based on document-descriptive and control information embedded in the printed output. These “smart” printing/copying techniques and controls allow a document user to control printing/copying costs by making tradeoffs with respect to quality and speed based on the embedded data. Such costs may be controlled, for example, by initially printing low cost (low quality, high speed) pages for distribution, while giving subsequent recipients of the document the option of making high quality (higher cost, possibly slower) copies of any or all of the pages in the document, if desired. With these features, a user is able to obtain high quality copies from low quality originals. The techniques of the present invention also allow a recipient to edit page content prior to reprinting, without loss of print output quality.

摘要： Disclosed are embodiments of systems and methods for eliminating or reducing the distortion in a scanned image. Embodiments of the present invention allow for the automatic pruning, de-skewing, and unwarping of an image using document layout information. In embodiments, dominant baselines may be selected by examining the letter regions on boundary baselines rather than examining the entire document layout. The dominant baselines may then be used to reduce distortion in the image. It shall be noted that present invention is robust enough to handle many types of content, including different languages, as well as documents with different layouts. The present invention may also be applied to images obtained from bound documents and flat documents.

摘要： Embodiments of the invention are described that provide automated and efficient optimization of camera settings. In certain embodiments of the invention, both focus and exposure settings are determined based on an analysis of compressed images taken of a frame. Based on this analysis, the camera focus and exposure settings are set to provide a preferred image quality of the particular frame. This optimization of the focus and exposure settings is performed at each frame within the multi-frame image source. As a result, each frame image is independently optimized and addresses variations, such as light and surface inconsistencies, across the multi-frame image source.
