Abstract: A method for content delivery includes receiving a request for delivery of a still image to a client terminal. A promotional image is selected to be delivered to the client terminal together with the still image. The still image and the promotional image are processed together so as to create an image sequence containing the still image and the promotional image in a moving picture format. Responsively to the request for delivery of the still image, the image sequence is delivered over a network for display in the moving picture format by the client terminal.

Abstract: A computer-implemented method for tracking multimedia content includes generating a first feature vector of a first multimedia object, extracting a second multimedia object from a transmission of digital traffic, generating a second feature vector of the second multimedia object, and determining a similarity of the second feature vector to the first feature vector. Responsively to the similarity, the second multimedia object is identified as an instance of the first multimedia object.

Abstract: A computer-implemented method for image adaptation includes accepting a digitally-represented input image and a target size requirement. The input image is modified by optimally determining at least one of a resolution of the input image and a quality of the input image, the quality defining an amount of information allocated to represent each pixel value of the input image, so as to produce a compressed output image meeting the target size requirement.
