20140016863 | APPARATUS AND METHOD FOR PERFORMING VISUAL SEARCH - A method comprises computing a color factor value indicating an amount of color gradients in at least one color channel from the query image. The method comprises combining the color-keypoints with the gray-keypoints when the color factor value is greater than a threshold. A method for performing a visual search comprises extracting a plurality of local descriptors from a query image and then selecting a subset of them based on various criteria's such as visual meaning score. A method comprises aggregating each mean vector for each visual codeword from distances between each visual codeword and local descriptors.

20140101195 | INCREMENTAL VISUAL QUERY PROCESSING WITH HOLISTIC FEATURE FEEDBACK - To reduce communication costs and computational complexity, only a subset of ranked SIFT points within a query image for a visual search request is transmitted to the visual search server in each iteration of an incremental search. For each candidate match, a flag identifying the matching points is returned by the server for use in computing holistic (e.g., histogram) information for a bounding box within the query image including the matching points. Distance from that query image holistic information is used to reject images from a short list used for a subsequent iteration, if any. If all images are rejected or a match criteria is met during one iteration, the search may terminate early without consideration of remaining SIFT points. | 04-10-2014 |
20140185941 | ROBUST KEYPOINT FEATURE SELECTION FOR VISUAL SEARCH WITH SELF MATCHING SCORE - 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. | 07-03-2014 |
20140195560 | TWO WAY LOCAL FEATURE MATCHING TO IMPROVE VISUAL SEARCH ACCURACY - 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. | 07-10-2014 |
20140198998 | NOVEL CRITERIA FOR GAUSSIAN MIXTURE MODEL CLUSTER SELECTION IN SCALABLE COMPRESSED FISHER VECTOR (SCFV) GLOBAL DESCRIPTOR - A wireless communication device includes a processor configured to execute an image query. The image query utilizes cluster selection criteria for a cluster-aggregation based vectorization of a set of local features based on a quantity of top local features having the highest posteriori probability values. The cluster selection criterion is measured as the summation of the posteriori probability values of the top local features. The quantity of top local features is determined by a predetermined integer value greater than one. | 07-17-2014 |
20140201200 | VISUAL SEARCH ACCURACY WITH HAMMING DISTANCE ORDER STATISTICS LEARNING - 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. | 07-17-2014 |
