    摘要： The image signature extraction device includes an extraction unit and a generation unit. The extraction unit extracts region features from respective sub-regions in an image in accordance with a plurality of pairs of sub-regions in the image, the pairs of sub-regions including at least one pair of sub-regions in which both a combination of shapes of two sub-regions of the pair and a relative position between the two sub-regions of the pair differ from those of at least one of other pairs of sub-regions. The generation unit generates, based on the extracted region features of the respective sub-regions, an image signature to be used for identifying the image.

    摘要： The present invention is to notify a recognition result with respect to a recognition object in a video in real time while maintaining recognition accuracy. A recognition object and m-number of first local characteristic quantities which are respectively 1-dimensional to i-dimensional characteristic vectors are stored in association with each other, and n-number of second local characteristic quantities which are respectively 1-dimensional to j-dimensional characteristic vectors are generated for n-number of local areas respectively including n-number of characteristic points from an image in a video. In addition, a smaller dimension is selected from the dimension i and the dimension j, a recognition that the recognition object exists in an image in the video is made when it is determined that a prescribed proportion or more of the m-number of first local characteristic quantities which are characteristic vectors up to the selected number of dimensions correspond to the n-number of second local characteristic quantities which are characteristic vectors up to the selected number of dimensions, and information representing the recognition object is displayed in superposition on an image in which the recognition object exists in the video.

    摘要： This image identity scale calculation system can calculate an identity scale representing a degree of identity of two images in consideration of identification capability and robustness. An image feature comparison unit is supplied with hierarchical quantization index codes, which are encodings allowing unique specification of quantization indexes of a plurality of hierarchies calculated by hierarchical quantization for each quantization target region of the two images, and selects a quantization index set used for comparison as a comparing quantization index set based on additionally supplied information in accordance with a previously defined hierarchical quantization method. Then, the image feature comparison unit compares the hierarchical quantization index codes of the two images by using the comparing quantization index set, and calculates an identity scale of the two images.
