  • Publication number: 20190147226
    Abstract: A method of matching a first person in a first image to a person in a second image. At least one companion in the first image is determined and being different to the first person. A contextual confidence for the first person, the companion and each of a plurality of people in the second image is determined, the contextual confidence being a measure of prediction accuracy of a match to the first person. An appearance score between each person in the first image and each of the plurality of people in the second image, the appearance score measuring similarity of appearance. The method selects from the plurality of people in the second image, a match for the first person and, based on the match for the first person, a match for the companion, each of the matches being determined according to the contextual confidence and appearance score.

  • Patent number: 10248860
    Abstract: A method of identifying, with a camera, an object in an image of a scene, by determining the distinctiveness of each of a number of attributes of an object of interest, independent of the camera viewpoint, determining the detectability of each of the attributes based on the relative orientation of a candidate object in the image of the scene, determining a camera setting for viewing the candidate object based on the distinctiveness of an attribute, so as to increase the detectability of the attribute, and capturing an image of the candidate object with the camera setting to determine the confidence that the candidate object is the object of interest.

  • Publication number: 20180374237
    Abstract: A method of determining a pose for an object. A plurality of images capturing the object at different viewpoints are received. The viewpoints are related by an angular distance with respect to the object. A feature vector is extracted for the object from each of the received images. Each extracted feature vector is compared with feature vectors from a database to determine a plurality of candidate poses. A pose of the object is determined by comparing candidate poses associated with different ones of the viewpoints, using the angular distance between the viewpoints with respect to the object.

  • Publication number: 20180173940
    Abstract: A method of matching a person in captured images comprises determining first feature vectors from a first image sequence of person(s), and determining second feature vectors from a second image sequence of person(s). The first and second feature vectors are determined based on properties of pixels located in the first and second image sequences respectively. The method further comprises, for a first feature vector corresponding to a first person in the first image sequence, determining a reference distance to one of the second feature vectors corresponding to a reference person in the second image sequence; determining a distance metric by constraining a distance between the first feature vector and a feature vector corresponding to the first person in the second image sequence, according to the determined reference distance; and matching a pair of images of the person in the captured images based on the distance metric.

  • Patent number: 9996752
    Abstract: A method and system associated with a camera view of a moving-object in a scene. The method comprises detecting and tracking the moving object over multiple video frames, estimating an orientation of the moving object in each of the video frames, and constructing a cost map from the estimated orientations over the multiple video frames for finding a minimum cost path over the cost map. The Method also comprises determining regularized orientation estimates of the moving-object from the minimum cost path, and locating the vanishing point of the camera view based on an axis of the moving-object from the minimum cost path, the axis formed by using the regularized orientation estimates.

  • Patent number: 9898686
    Abstract: A method of identifying an object in an image is disclosed. At least one feature map for each of a plurality of cells in the image is determined. A self-dissimilarity between a first feature map associated with a first one of said cells and a second feature map associated with a second cell, is determined.

An appearance signature for the object is formed based on the determined self-dissimilarity. A distance between the appearance signature of the object in the image and appearance signatures of each of a plurality of further objects is determined. The object in the image is identified based on the determined distances.

  • Patent number: 9799124
    Abstract: A method of determining a property of an image (176) captured by a camera (127). Vanishing points (320, 330, 340) are in the image (176). Each pixel of the image (176) is associated with one or more of the vanishing points (320, 330, 340) based on an orientation of the image gradient at the pixel. The image is partitioned into a set of regions associated with a pair of the determined vanishing points based on the vanishing point associations for pixels in the image (176). Boundaries of the regions are aligned with the associated vanishing points. For at least one of the plurality of regions, a confidence value is determined for the property of the image based on pixels in the region. The property of the image is determined for one or more pixels within the image (176) based on the confidence value.
