摘要： A computer implemented method tracks 3D positions of an object moving in a scene. A sequence of images is acquired of the scene with a set of cameras such that each time instant a set of images are acquired of the scene, in which each image includes pixels. Each set of images is aggregated into a synthetic aperture image including the pixels, and the pixels in each the set of images are matched corresponding to multiple locations and multiple depths of a target window with an appearance model to determine scores for the multiple locations and multiple depths. A particular location and a particular depth having a maximal score is selected as the 3D position of the moving object.

摘要： Various embodiments of a system and methods for real-time image collection and sharing are described. A group of geographically co-located mobile device users may capture images on the mobile devices during a session. The devices may send the images, during the same session, to a database where the images may be stored as a real-time image collection. The image collection may be shared, during the same session, among the mobile device users. The users may receive notification of new images in the image collection based on user preferences. The users may request, from the image collection, images containing particular content by identifying the content on an image and sending a search request which includes the identified content. A computation server may maintain a data set which associates similar images in the image collection. The data set may be updated for each new image that is added to the image collection.

摘要： A method extracts an alpha matte from images acquired of a scene by cameras. A depth plane is selected for a foreground in the scene. A trimap is determined from a set of images acquired of the scene. An epipolar plane image is constructed from the set of images and the trimap, the epipolar plane image including scan lines. Variances of intensities are measured along the scan lines in the epipolar image, and an alpha matte is extracted according to the variances.

摘要： A method and system for determining an alpha matte for a video is presented. A set of videos is acquired by an array of cameras. A centrally located camera in the array is designated as a reference camera and acquires a reference video. A foreground depth plane is selected from the set of videos. A trimap is determined from variances of pixel intensities in each image. Variances of the intensities of pixels labeled as background and pixels labeled as foreground are extrapolated to the pixels labeled as unknown in the trimap. Means of the intensities of the pixels labeled as background are extrapolated to the pixels labeled as unknown to determine an alpha matte for the reference video.

摘要： A system and method for expansion and reduction of images in an image editing application uses the frequency of pixels values (e.g., absolute color and/or intensity values) of an input image to determine respective energy values for each pixel of the image. The energy values may vary inversely with the frequency of the pixel values. The energy values may be used to determine one or more low-cost seams of the image to be removed for an image reduction operation or replicated for an image expansion operation, where the cost of each seam is dependent on the energy values of the pixels of the seam. Determining the frequency of pixel values of the image may involve determining the number of pixels having an absolute pixel value in each of a plurality of pixel value ranges, and the absolute pixel values included in each range may be configurable by the user.

摘要： A method for content-aware image retargeting generates an energy image from a source image according to an energy function. From the energy image, one or more seams are determined according to a minimizing function such that each seam has a minimal energy. Each seam is applied to the source image to obtain a target image that preserves content and a rectangular shape of the source image.
