20080219587 | Method for Retargeting Images - 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. | 09-11-2008 |

20090092282 | System and Method for Tracking Objects with a Synthetic Aperture - 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. | 04-09-2009 |
20100027876 | Seam-Based Reduction and Expansion of Images With Color-Weighted Priority - A system and method for expansion and reduction of images uses an absolute value associated with each pixel of an input image (e.g., a color and/or intensity value) to determine a respective energy value for each pixel. For example, a given color or range of colors (e.g., skin tones, or other high-priority colors) may be assigned higher energy values than other colors and/or color ranges, and may be protected during image reduction and/or expansion. These energy values may be used to determine a cost associated with various seams of the image, which may represent the priority of the seams in the image. One or more low-cost seams may be identified for removal or replication to produce a resized image. The methods may be used in conjunction with an automated skin tone detector or a user interface that allows selection of one or more high priority colors or color ranges. | 02-04-2010 |
20110211771 | Content Aware Resizing of Images and Videos - A method resizes input images by first constructing a grid graph. The grid graph includes one node for each pixel in the input image, and adjacent nodes in the grid graph are connected by arcs. Each arc is directed and has an associated cost. A cut is applied to the arcs of the grid graph using a cost function. A seam of pixels is determined from the cut so that coordinates of the pixels in the seam enforce monotonicity and connectivity constraints. Then, the input image is resized according to the seam to produce an output image while minimizing a change of energy in the output image when compared with the input image. | 09-01-2011 |
20130124508 | SYSTEM AND METHOD FOR REAL-TIME IMAGE COLLECTION AND SHARING - 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. | 05-16-2013 |
20130125069 | System and Method for Interactive Labeling of a Collection of Images - Various embodiments of a system and method for labeling images are described. An image labeling system may label multiple images, where each of the images may be labeled to identify image content or image elements, such as backgrounds or faces. The system may display some of the labeled image elements in different portions of a display area. Unlabeled image elements may be displayed in the same display area. The display size and position of each unlabeled image element may be dependent on similarities between the unlabeled image element and the displayed, labeled image elements. The system may also receive gesture input in order to determine a corresponding labeling task to perform. | 05-16-2013 |
20130129231 | System and Method for Labeling a Collection of Images - Various embodiments of a system and methods for labeling images are described. An image labeling system may receive multiple images. A subset of the images may be labeled to identify image content or elements, such as faces. The system may display some of the labeled image elements in different portions of a display area. Unlabeled image elements may be displayed in the same display area. The display size and position of each unlabeled image element may be dependent on similarities between the unlabeled image element and the displayed, labeled image elements. The system may receive input which indicates that one or more of the displayed, unlabeled image elements should receive the same label as one of the displayed, labeled image elements. Similarities between image elements may be re-analyzed, dependent on the assigned labels, and the display of unlabeled images may be updated. | 05-23-2013 |
20130129316 | Methods and Apparatus for Tutorial Video Enhancement - A plurality of segment transitions in a video data stream is identified. The identifying the plurality of segment transitions includes recognizing an interface feature of a first application interface displayed in the video data stream and generating metadata associating a selected segment transition with a particular point in the video data stream. The interface feature indicates the selected segment transition among the plurality of segment transitions in the video data stream. A navigation system for navigating among the plurality of segment transitions in the video data stream is provided. Responsive to input, navigation to the selected segment transition is performed and the video data stream is displayed from the particular point. | 05-23-2013 |
