摘要： A method described herein includes acts of receiving a sequence of images of a scene and receiving an indication of a reference image in the sequence of images. The method further includes an act of automatically assigning one or more weights independently to each pixel in each image in the sequence of images of the scene. Additionally, the method includes an act of automatically generating a composite image based at least in part upon the one or more weights assigned to each pixel in each image in the sequence of images of the scene.

摘要： A method is disclosed for stitching together first and second sets of images from three or more image sensors. The first set of images are combined into a composite left view of the panorama, and the second set of images are combined into a composite right view of the panorama. When properly stitched together, the left and right views may be presented as a stereoscopic view of the panorama. A stitching algorithm is applied which removes any disparity due to the parallax in the combined left images and in the combined right images.

摘要： An image enhancement system may match images to a matrix having various enhancements of images for groups of users. The matrix may define image enhancement settings for the particular images and groups of users, and the matching may apply enhancements to a new image that closely matches a user's preferences. After the matrix is initially populated, new users and new images may be added to increase the matrix's accuracy. The image enhancement system may be deployed as a cloud service, where images may be enhanced as a standalone application or as part of a social network or image sharing website. In some embodiments, the image enhancement system may be deployed on a personal computer or as a component of an image capture device.

摘要： Systems and methods are disclosed for generating panoramic stereoscopic images. The system includes an assembly of three or more catadioptric image sensors affixed to each other in a chassis. Each image sensor generates a catadioptric image of a panorama, which may for example be a 360° view of a scene. The software components process the catadioptric image to a 3D stereoscopic view of a panorama.

摘要： Described is a user interface that displays a representation of a stereo scene, and includes interactive mechanisms for changing parameter values that determine the perceived appearance of that scene. The scene is modeled as if viewed from above, including a representation of a viewer's eyes, a representation of a viewing screen, and an indication simulating what each of the viewer eyes perceives on the viewing screen. Variable parameters may include a vergence parameter, a dolly parameter, a field-of-view parameter, an interocular parameter and a proscenium arch parameter.

摘要： Stereoscopic image display is described. In an embodiment, a location of the eye pupils of a viewer is determined and tracked. An image is displayed within a first focus for viewing with the left eye of the viewer, and the image is displayed within a second focus for viewing with the right eye of the viewer. A positional change of the eye pupils is tracked and a sequential image that corresponds to the positional change of the eye pupils is generated for stereoscopic viewing. In another embodiment, an image is displayed for stereoscopic viewing and a head position of a viewer relative to a center of the displayed image is determined. A positional change of the viewer's head is tracked, and a sequential image that corresponds to the positional change of the viewer's head is generated for stereoscopic viewing.

摘要： An “Image Denoiser” provides a probabilistic process for denoising color images by segmenting an input image into regions, estimating statistics within each region, and then estimating a clean (or denoised) image using a probabilistic model of image formation. In one embodiment, estimated blur between each region is used to reduce artificial sharpening of region boundaries resulting from denoising the input image. In further embodiments, the estimated blur is used for additional purposes, including sharpening edges between one or more regions, and selectively blurring or sharpening one or more specific regions of the image (i.e., “selective focus”) while maintaining the original blurring between the various regions.

摘要： A system and process for determining the vignetting function of an image and using the function to correct for the vignetting is presented. The image can be any arbitrary image and no other images are required. The system and process is designed to handle both textured and untextured segments in order to maximize the use of available information. To extract vignetting information from an image, segmentation techniques are employed that locate image segments with reliable data for vignetting estimation. Within each image segment, the system and process capitalizes on frequency characteristics and physical properties of vignetting to distinguish it from other sources of intensity variation. The vignetting data acquired from segments are weighted according to a presented reliability measure to promote robustness in estimation.

摘要： A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash. A second image is taken of the same subject matter with the use of flash. The foreground information in the flash image is illuminated by the flash to a much greater extent than the background information. Based on this property, the strategy applies processing to extract the foreground information from the background information. The strategy supplements the flash information by also taking into consideration motion information and color information.
