  • Patent number: 9633265
    Abstract: A method for tracking objects across a number of image frames includes tracking objects in the frames based on appearance models of each foreground region corresponding to each of the objects and determining if a plurality of the tracked objects overlap. Where a plurality of the tracked objects overlap, the method creates compensated appearance models for each of the plurality of overlapping objects by attenuating common appearance features among the corresponding appearance models; and tracks the plurality of overlapping objects based on the created compensated appearance models.

  • Patent number: 9633284
    Abstract: The degree of similarity between corresponding local feature amounts out of a plurality of local feature amounts of the object in the input image and a plurality of local feature amounts of an object in an image registered in advance is obtained. At least one degree of similarity is selected out of the obtained degrees of similarity based on a capturing condition for the object in the input image and a capturing condition for the object in the registered image, and one degree of similarity is derived from the at least one selected degree of similarity. It is determined based on the one derived degree of similarity whether the object in the input image belongs to the same category as the object in the registered image.

  • Patent number: 9633264
    Abstract: Each of a plurality of cameras is sequentially selected. An image that does not include a retrieval target object is acquired, as a background image, from an image group captured by a selected camera. An image including the retrieval target object is acquired as a query image. A discriminator being used for identifying the retrieval target object from the image captured by the selected camera is learned using the background image and the query image. The retrieval target object is retrieved from the image group captured by the selected camera using the learned discriminator.

  • Patent number: 9634897
    Abstract: A communication apparatus capable of activating an EEE power saving mode when not activated. The communication apparatus is operable in an auto-negotiation mode. When a CPU of the communication apparatus determines that a power saving mode to be realized in the auto-negotiation mode is to be activated, if an other-party apparatus at the other end of communication has been set to a fixed mode, the CPU causes the other-party apparatus to be set to the auto-negotiation mode.
