Abstract:
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.

Abstract:
The method and system of this invention predictively encodes and decodes an image signal that has been treated with the Roberts Method. The method and system generates a noise signal that is substantially similar to the noise signal generated during the Roberts Method treatment, calculates a range of values for the original image signal based upon an image signal from a different pixel location, predicts the image signal based upon the range of values and the noise signal and calculates an error signal that is encoded. The decoding method and system operates in reverse of the encoding method and system.
Abstract:
A method for processing digital images to be displayed, stored, or printed, to eliminate blooming and other artifacts. The system utilizes morphological processes to isolate and modify image structures susceptible to marking process artifacts and then combines the modified image structures with the input image to produce a printable image that may be rendered on a given printer.
Abstract:
The present invention is a method and apparatus for reducing two-color moire often found during the rendering of full color images using halftoning techniques. The invention relies upon the application of a non-periodic halftone operation to the least perceptible color separation (e.g., yellow) so as to prevent the formation of periodic structures due to the interaction of the yellow colorant with one of the other colorants (e.g., cyan or magenta).

Abstract:
A method and apparatus for converting the resolution of an input image to a higher resolution that is a noninteger multiple of the input resolution. The method and apparatus employ either an interlocked or noninterlocked clustering arrangement of output pixels in order to assign to each output pixel a reference value determined from the signal levels of the input image. In addition, the method and apparatus include a template-based enhancement filter to further refine modify or alter the assigned signal level prior to its output as a higher resolution image.
Abstract:
An apparatus for determining a background level of an image to be scanned. The apparatus builds a series of histograms of the image each corresponding to a line of the image, analyzes each of the histograms, and averages the results of the analysis, to continually update a background level during the scan of the image. The apparatus may be implemented with a simple architecture capable of operating at high speed.
Abstract:
A method for determining local defocus distance in a scanned image of a non-planar original object is provided comprising scanning at least a portion of the non-planar original object to produce first scanned image data at a first focal plane and scanning same the at least a portion of the non-planar original object to produce at least second scanned image data at a second focal plane. The first scanned image data is different from the second scanned image data wherein a distance between the first focal plane and the second focal plane is a predetermined quantity. The method further comprises estimating an out-of-focus distance of the object from the first and the second scanned image data.
