Abstract: We propose methods for generating a halftone image, in which each pixel takes one of two tone values. The generated image contains hidden data, which is present at data storage pixels chosen using a pseudo-random number generator. In a first case, the data is hidden within an existing halftone image by reversing the tone value at certain of the data storage pixels, and at pixels neighboring the data storage pixels. In a second case, the halftone image is generated from a grey-scale image, and data is hidden during this conversion process.

Abstract: A device and method for converting one stereoscopic format into another. A software-enabled matrix is used to set forth predefined relationships between one type of format as an input image and another type of format as an output image. The matrix can then be used as a look-up table that defines a correspondence between input pixels and output pixels for the desired format conversion.

Abstract: A method, system and storage arrangement are provided for effectuating an evaluation and analysis of anatomical structures, and creating and/or modifying images associated therewith. In particular, at least two images associated with the anatomical structure can be normalized so as to produce normalized image. A normalized set of regions of interest can be obtained based on the normalized images. Each of the normalized set of regions of interest may be analyzed to provide analysis data. Further, the anatomical structure mask may be created and/or modified based on the analysis data. Another embodiment provides for rating and analyzing anatomical structures.

Abstract: The AC and/or PC landmarks are identified in a midsagittal MRI image by firstly identifying structures in the brain (specifically the fornix and/or brainstem) as groups of pixels in a radiological image which have an intensity in ranges defined by one or more thresholds and which obey predefined geometrical criteria. The thresholds are varied until the predefined geometrical criteria are met. Initial estimates of the position of the AC and/or PC are derived from the identified structures. These estimates can be improved in various ways, especially by making use of axial and/or corona/radiological images in planes including, and/or proximate to, the initial estimated position of the AC and/or PC.

Abstract: At least one embodiment of the present application relates to a method and/or an apparatus for determining the concentration of a substance in a body material that is composed of two different material components in an unknown ratio. In an embodiment of the method, two computed tomography pictures from which two image data records are reconstructed are recorded in conjunction with two different spectral distributions of the x-radiation. The x-ray attenuation values for each voxel of the two image data records are decomposed into three material components. The decomposition is performed on the assumption that the x-ray attenuation value xM of the body material without the substance is composed of the x-ray attenuation values xM1, xM2 of the first and second material component in accordance with the following equation: xM=f*xM1+(1-f)*XM2, f being a volume fraction of the first material component in the body material.

Surrounding structures are used as high-level constraints to construct shape and appearance models. Prior shape information is integrated for the segmentation of a new esophagus using a Bayesian formulation. This permits to automatically select the proper models. Given the end points, a shortest path algorithm provides the optimal esophagus according to the Bayesian formulation.

Abstract: User attribute data, such as a retinal scan or fingerprint data, is encoded into a media signal as it is captured in media capture device, such as a camera, video recorder, etc. The user attribute data uniquely associates the creator with the content he or she creates. By steganographically embedding the user attribute data into the content at or near the time of capture, the creator of the content can be authenticated at a subsequent time. In addition, alteration of the content can be detected.

Abstract: This document discusses, among other things, systems and methods that track overall time for processing operations such that the processing time can be shared among the resources in an efficient manner. Processing time can be shifted to image processing where the time will provide the most benefit to image quality. Moreover, access time from one process is banked to be used by a subsequent process or on a subsequent group of pixels. This document also discusses, among other things, systems and methods that provide additional processing power on an as needed basis. In an example, a processing stage and its controller are outside the normal pixel processing flow path. When it is determined that additional processing is required, the processing stage and its controller are activated to perform the additional processing.

A plurality of loci associated with a model of skeletal structure of a knee joint are fitted and used to parameterize positions of the plurality of loci in a given subject and, thereby, to derive parameters of a deformable statistical template. The skeletal morphology is then characterized on the basis of the derived parameters of the deformable statistical template.

Abstract: An optical system for determining the angular position of a radiating point source is disclosed, wherein radiation from a point source travels through a mask and onto the surface of a sensor. A preferred embodiment employs a plurality of mask transmission frequencies and a detector designed to be sensitive to the phases of the frequencies. A computer measures the phases of a plurality of detected image frequencies. Measurement of the particular phases of the frequency components allows determination of the image shift on the detector axis. The image shift is then used to compute angle of incidence of the light source upon the detector. The preferred embodiment employs a refractive window, hence the angle of incidence between point radiating source and mask are determined using the window index of refraction and refraction equations. Applications include within the cockpit of a jet aircraft.
