摘要： A process for color graphics image processing, related to detection and segmentation of sweeps, is provided. An input graphics image is transformed into a three-dimensional histogram in an appropriate color space 104 (e.g., CIELUV). Two-dimensional histograms are estimated from the three-dimensional histogram 106. The two-dimensional histograms are processed to detect and segment sweeps 108. Sweep segment information from the processing of the two-dimensional histograms is combined 110. The combined sweep segment information is used to process the input graphics image to identify and segment sweeps 112. Post-processing may be optionally and selectively used to reject false alarms (i.e., areas falsely identified as sweeps) 114.

摘要： A method and system for image processing, in conjunction with classification of images between natural pictures and synthetic graphics, using SGLD texture (e.g., variance, bias, skewness, and fitness), color discreteness (e.g., R—L, R—U, and R—V normalized histograms), or edge features (e.g., pixels per detected edge, horizontal edges, and vertical edges) is provided. In another embodiment, a picture/graphics classifier using combinations of SGLD texture, color discreteness, and edge features is provided. In still another embodiment, a “soft” image classifier using combinations of two (2) or more SGLD texture, color discreteness, and edge features is provided. The “soft” classifier uses image features to classify areas of an input image in picture, graphics, or fuzzy classes.

摘要： The invention comprises an imaging apparatus housed within a mobile device housing, and configured to enable multiple image acquisition modes. The apparatus includes an image sensor, a first optical assembly, a second optical assembly and a controller. The first optical assembly of the invention is positioned over a first image capture region of the imaging surface, and defines a first field of view—such that the first optical assembly images onto the first image capture region, any object plane within the first field of view. The second optical assembly is positioned over a second image capture region of the imaging surface, and defines a second field of view—such that the second optical assembly images onto the second image capture region, any object plane within the second field of view. The invention additionally includes a corresponding method for enabling multiple image acquisition modes in an imaging apparatus.
