Abstract: An image processing system and method corrects the perceptual quality of an image by adjusting the image colors. “Color” in this sense is to be understood as encompassing three-dimensional parameterizations of color, incorporating both intensity and hue. These measurements are made using creative computations developed and adapted from the RETINEX™ theory (Land, 1977), where the RETINEX implementation adjusts any pixel in any direction in color space and further to automatically determine the best direction for it to be adjusted to increase the perceptual visibility of the algorithm with a minimal amount of change to the original image values.

Abstract: Discovering mixtures of models includes: initiating learning algorithms, determining, data sets including a cluster of points in a first region of a domain and a set of points distributed near a first line extending across the domain; inferencing parameters from the cluster and the set of points; creating a description of the cluster of points in the first region of the domain and computing approximations of a first learned mixture model and a second learned mixture model; determining a first and second probability, generating a confidence rating that each point of the cluster of points in the first region of the domain corresponds to the first learned mixture model and generating a confidence rating that each point of the set of points distributed near the first line correspond to the second learned mixture model, thus causing determinations of behavior of a system described by the learned mixture models.

Abstract: Methods and systems of representation and manipulation of surfaces with perceptual geometric features, using a computer graphics rendering system, include executing algorithmic instructions to compute a plurality of vertices, edges and surfaces in a mesh for the purpose of defining representations of surfaces on grids. Normals and distances are determined for triangular surfaces to be considered. Additionally, height fields of a function are defined. A set of feature curves and a set of feature points are determined, based on the defined function. Infinitesimal movements along the representations of the surfaces are determined, along with determinations of properties of representations of continuous surfaces. Additional determinations of perceptual geometric features include determinations such as zero crossings, parabolic curves, flecnodes, ruffles, gutterpoints, conical points and biflecnodes in a given mesh.

Abstract: A system is provided for selecting a particular barcode on an item that includes multiple barcodes. The system (1) acquires, via a barcode imager, an image of the item within the field of view of the barcode imager, (2) analyzes the acquired image to determine a set of potential barcode fields, (3) determines, using a predetermined criterion (e.g., distance from center of imaged area, type of bar code, etc.), a candidate barcode field from among the set of potential barcode fields, (4) displays a modified image derived from the acquired image, wherein the candidate barcode field is identified within the modified image, and (5) allows the user to initiate a decode session when the candidate barcode field includes the desired barcode.
