20090157503 | PYRAMIDAL VOLUMES OF ADVERTISING SPACE - The claimed subject matter relates to an architecture that can facilitate advertising models in connection with pyramidal volumes of advertising space. In particular, a pixel at one plane of view of an image can be associated with four pixels at a lower plane of view and so on. Advertising rights with respect to the pixel can be offered for sale, which can include all, a subset, or a different set of advertising rights with respect to other pixels in the pyramidal volume. The architecture can construct the data for the image dynamically based upon contextual input and the advertising rights as well as image format can be constructed based upon notions of zoning. | 06-18-2009 |
20090263045 | IMAGE BLENDING USING MULTI-SPLINES - Multi-spline image blending technique embodiments are presented which generally employ a separate low-resolution offset field for every image region being blended, rather than a single (piecewise smooth) offset field for all the regions to produce a visually consistent blended image. Each of the individual offset fields is smoothly varying, and so is represented using a low-dimensional spline. A resulting linear system can be rapidly solved because it involves many fewer variables than the number of pixels being blended. | 10-22-2009 |
20090310888 | MULTI-PASS IMAGE RESAMPLING - Multi-pass image resampling technique embodiments are presented that employ a series of one-dimensional filtering, resampling, and shearing stages to achieve good efficiency while maintaining high visual fidelity. In one embodiment, high-quality (multi-tap) image filtering is used inside each one-dimensional resampling stage. Because each stage only uses one-dimensional filtering, the overall computation efficiency is very good and amenable to graphics processing unit (GPU) implementation using pixel shaders. This embodiment also upsamples the image before shearing steps in a direction orthogonal to the shearing to prevent aliasing, and then downsamples the image to its final size with high-quality low-pass filtering. This ensures that none of the stages causes excessive blurring or aliasing. | 12-17-2009 |
20100238164 | IMAGE STITCHING USING PARTIALLY OVERLAPPING VIEWS OF A SCENE - An “Oblique Image Stitcher” provides a technique for constructing a photorealistic oblique view from a set of input images representing a series of partially overlapping views of a scene. The Oblique Image Stitcher first projects each input image onto a geometric proxy of the scene and renders the images from a desired viewpoint. Once the images have been projected onto the geometric proxy, the rendered images are evaluated to identify optimum seams along which the various images are to be blended. Once the optimum seams are selected, the images are remapped relative to those seams by leaving the mapping unchanged at the seams and interpolating a smooth mapping between the seams. The remapped images are then composited to construct the final mosaiced oblique view of the scene. The result is a mosaic image constructed by warping the input images in a photorealistic manner which agrees at seams between images. | 09-23-2010 |
20110176043 | Reducing Motion-Related Artifacts in Rolling Shutter Video Information - A system is described for reducing artifacts produced by a rolling shutter capture technique in the presence of high-frequency motion, e.g., produced by large accelerations or jitter. The system operates by computing low-frequency information based on the motion of points from one frame to the next. The system then uses the low-frequency information to infer the high-frequency motion, e.g., by treating the low-frequency information as known integrals of the unknown underlying high-frequency information. The system then uses the high-frequency information to reduce the presence of artifacts. In effect, the correction aims to re-render video information as though all the pixels in each frame were imaged at the same time using a global shutter technique. An auto-calibration module can estimate the value of a capture parameter, which relates to a time interval between the capture of two subsequent rows of video information. | 07-21-2011 |
20120169734 | Navigating Images Using Image Based Geometric Alignment And Object Based Controls - Over the past few years there has been a dramatic proliferation of digital cameras, and it has become increasingly easy to share large numbers of photographs with many other people. These trends have contributed to the availability of large databases of photographs.

20120237111 | Performing Structure From Motion For Unordered Images Of A Scene With Multiple Object Instances - A technology is described for performing structure from motion for unordered images of a scene with multiple object instances. An example method can include obtaining a pairwise match graph using interest point detection for obtaining interest points in images of the scene to identify pairwise image matches using the interest points. Multiple metric two-view and three-view partial reconstructions can be estimated by performing independent structure from motion computation on a plurality of match-pairs and match-triplets selected from the pairwise match graph. Pairwise image matches can be classified into correct matches and erroneous matches using expectation maximization to generate geometrically consistent match labeling hypotheses and a scoring function to evaluate the match labeling hypotheses. A structure from motion computation can then be performed on the subset of match pairs which have been inferred as correct. | 09-20-2012 |
20120321175 | LOCATION-AIDED RECOGNITION - A mobile device having the capability of performing real-time location recognition with assistance from a server is provided. The approximate geophysical location of the mobile device is uploaded to the server. Based on the mobile device's approximate geophysical location, the server responds by sending the mobile device a message comprising a classifier and a set of feature descriptors. This can occur before an image is captured for visual querying. The classifier and feature descriptors are computed during an offline training stage using techniques to minimize computation at query time. The classifier and feature descriptors are used to perform visual recognition in real-time by performing the classification on the mobile device itself. | 12-20-2012 |

20080240551 | LOCAL BI-GRAM MODEL FOR OBJECT RECOGNITION - A local bi-gram model object recognition system and method for constructing a local bi-gram model and using the model to recognize objects in a query image. In a learning phase, the local bi-gram model is constructed that represents objects found in a set of training images. The local bi-gram model is a local spatial model that only models the relationship of neighboring features without any knowledge of their global context. Object recognition is performed by finding a set of matching primitives in the query image. A tree structure of matching primitives is generated and a search is performed to find a tree structure of matching primitives that obeys the local bi-gram model. The local bi-gram model can be found using unsupervised learning. The system and method also can be used to recognize objects unsupervised that are undergoing non-rigid transformations for both object instance recognition and category recognition. | 10-02-2008 |
