A hybrid image is an image that is perceived in one of two different ways, depending on viewing distance, based on the way humans process visual input. A technique for creating hybrid images exhibiting this optical illusion was developed by Aude Oliva of MIT and Philippe G. Schyns of University of Glasgow, a method originally proposed by Schyns and Oliva in 1994. Hybrid images combine the low spatial frequencies of one picture with the high spatial frequencies of another picture, producing an image with an interpretation that changes with viewing distance.
Target orientation estimation using depth sensing
A system for estimating orientation of a target based on real-time video data uses depth data included in the video to determine the estimated orientation. The system includes a time-of-flight camera capable of depth sensing within a depth window. The camera outputs hybrid image data (color and depth). Segmentation is performed to determine the location of the target within the image. Tracking is used to follow the target location from frame to frame. During a training mode, a target-specific training image set is collected with a corresponding orientation associated with each frame. During an estimation mode, a classifier compares new images with the stored training set to determine an estimated orientation. A motion estimation approach uses an accumulated rotation / translation parameter calculation based on optical flow and depth constrains. The parameters are reset to a reference value each time the image corresponds to a dominant orientation.

Method and System for Propagation of Myocardial Infarction from Delayed Enhanced Cardiac Imaging to Cine Magnetic Resonance Imaging Using Hybrid Image Registration
ActiveUS20120121154A1Correction of deformationAccurate alignment and deformation correctionImage enhancementImage analysisCine mriCardiac phase
A method and system for propagation of myocardial infarction from delayed enhanced magnetic resonance imaging (DE-MRI) to cine MRI is disclosed. A reference frame is selected in a cine MRI sequence. Deformation fields are calculated within the cine MRI sequence to register the frames of the cine MRI sequence to the reference frame. A DE-MRI image having an infarction region is registered to the reference frame of the cine MRI sequence. The DE-MRI image may be registered to the infarction region using a hybrid registration algorithm that unifies both intensity and feature points into a single cost function. Infarction information in the DE-MRI image is then propagated cardiac phases of the frames in the cine MRI sequence based on the registration of the DE-MRI image to the reference frame and the plurality of deformation fields calculated within the cine MRI sequence.

Hybrid infrared detector array and CMOS readout integrated circuit with improved dynamic range
ActiveUS20060181627A1High gainReduced dynamic rangeTelevision system detailsTelevision system scanning detailsIndium bumpDetector array
A hybrid image sensor includes an infrared detector array and a CMOS readout integrated circuit (ROIC). The CMOS ROIC is coupled to at least one detector of the IR detector array, e.g., via indium bump bonding. Each pixel of the CMOS ROIC includes a first, relatively lower gain, wide dynamic range amplifier circuit which is optimized for a linear response to high light level input signals from the IR detector. Each pixel also includes a second, relatively higher gain, lower dynamic range amplifier circuit which is optimized to provide a high signal to noise ratio for low light level input signals from the IR detector (or from a second IR detector). A first output select circuit is provided for directing the output of the first circuit to a first output multiplexer. A second output select circuit is provided for directing the output of the second circuit to a second output multiplexer. Thus, separate outputs of the first and second circuits are provided for each of the individual pixel sensors of the CMOS imaging array.

Techniques for creating a High Dynamic Range (HDR) image within a consumer grade digital camera from a series of images of a scene captured at different exposure levels, and displaying the HDR image on the camera's built-in display are provided. The approach employs mixing images of the series to incorporate both scene shadow and highlight details, and the removing of “ghost” image artifacts appearing in the mixed HDR image resulting from movement in the scene over the time the series images are captured. The low computational resource utilization of the image mixing and ghost removal processing operations, along with the ability to commence image mixing and ghost removal prior to the acquisition of all series images, can significantly reduce the time required to generate and display a tone mapped HDR image.

Method of Customizing 3D Computer-Generated Scenes
InactiveUS20090021513A1Low costRapid production3D-image renderingComputer graphics (images)The Internet
An automated method of rapidly producing customized 3D graphics images in which various user images and video are merged into 3D computer graphics scenes, producing hybrid images that appear to have been created by a computationally intensive 3D rendering process, but which in fact have been created by a much less computationally intensive series of 2D image operations. To do this, a 3D graphics computer model is rendered into a 3D graphics image using a customized renderer designed to automatically report on some of the renderer's intermediate rendering operations, and store this intermediate data in the form of metafilm. User images and video may then be automatically combined with the metafilm, producing a 3D rendered quality final image with orders of magnitude fewer computing operations. The process can be used to inexpensively introduce user content into sophisticated images and videos suitable for many internet, advertising, cell phone, and other applications.

A system and method for creating a combined or mixed-energy image using both low- and high-energy CT data sets acquired using a dual-energy CT system. The low- and high-energy datasets are mixed using desired weighting factors to mimic a “single-energy” image. The low-energy dataset provides data with improved contrast enhancement, but with increased noise level. The high-energy dataset provides data with lower contrast enhancement, but with better noise properties. By combining the low- and high-energy datasets in accordance with the present method, the resulting mixed-energy images utilize the information of full dose of radiation used in the dual-energy scan. A plurality of weighting metrics can be selected, including patient size, dose partitioning, or image quality, to determine the desired weighting factors based on the weighting metrics. By selecting the proper weight factors, image noise can be reduced and / or the contrast to noise ratio can be increased in the mixed-energy image.
