Abstract: To improve precision of visual search processing, SIFT points within a query image are forward matched to features in each of a plurality of repository images and SIFT points within each repository image are backward matched to features within the query image. Forward-only, backward-only and forward-and-backward matches may be weighted differently in determining an image match. Two way matching may be triggered by query image bit rate in excess of a threshold or by a sum of weighted distances between matching points exceeding a threshold. Significant performance gains in eliminating false positive matches are achieved.

Abstract: Global descriptors for images within an image repository accessible to a visual search server are compared based on order statistics processing including sorting (which is a non-linear transform) and heat kernel matching. Affinity scores are computed for Hamming distances between Fisher vector components corresponding to different clusters of global descriptors from a pair of images and normalized to [0, 1], with zero affinity scores assigned to non-active cluster pairs. Linear Discriminant Analysis is employed to determine a sorted vector of affinity scores to obtain a new global descriptor. The resulting global descriptors produce significantly more accurate matching.

Abstract: A method and apparatus control receiving media data in a transmission system. A method of operating a receiving entity in the transmission system includes receiving packets for media data and information about a fixed delay associated with the media data. The method also includes identifying a requirement configured to guarantee that the packets for the media data are delivered to an upper layer of the receiving entity after the fixed delay, from the information about the fixed delay. The method further includes identifying a buffer size requirement for the receiving entity estimated based on the fixed delay and Nitrate information associated with the media data; and delivering the packets to the upper layer of the receiving entity.

Abstract: To improve feature selection accuracy during a visual search, interest points within a query image are two-way matched to features in an affine transformed image or otherwise transformed version of the query image. A user device implements a method for selecting local descriptors in the visual search. The method includes: detecting a first set of interest points for the original image; computing an affine transform matrix; computing a new image as a transformation of the original image using the affine transform matrix; detecting a second set of interest points from the and new image; performing a two-way matching between the first set of interest points and the second set of interest points; sorting matching pairs according to a specified self-matching score (SMS); assigning an infinite value to SMS of unmatched interest points from the original image; selecting the interest points based on SMS. Significant performance gains reduce false positive matches.

Abstract: A method includes calculating a complexity value for each segment or version of multimedia content. The multimedia content has multiple versions associated with common content and different encoding parameters, and each version is divided into segments. The method also includes adaptively streaming the multimedia content to a client device based on at least some of the calculated complexity values. The complexity value for each segment or version is calculated by summing multiple operation complexity values defining complexities of operations for decoding the segment or version. The operation complexity values could include values for a bit parsing operation, a buffer initialization operation, an intra-prediction operation, an inverse quantization and transform operation, a reference block fetch operation, a fractional interpolation operation, and in-loop deblocking operation, a sample adaptive offset correction operation, an adaptive loop filtering operation, and a de-ringing filtering operation.

Abstract: A method for obtaining content includes determining that a playout of one or more other pieces of content is dependent upon a playout of a first piece of content. The method also includes obtaining the first piece of content and identifying a forced content token associated with the first piece of content. The method further includes obtaining an access token using the forced content token. In addition, the method includes using the access token to obtain the one or more other pieces of content. The forced content token could be identified as a hash of the first piece of content or as a watermark extracted from the first piece of content. The forced content token could also be identified by creating a thumbnail for each of one or more frames in the first piece of content and calculating a differential trace signature for each of the one or more frames.
