Still Image Database Management

We are particularly interested in large image bases, like those managed by photo agencies. These agencies have between five hundred thousands and twelve millions of images. The Andia Press agency has a million of them, Sigma twelve millions, the Corbis agency which gathers the whole of acquisitions of Bill Gates has thirty six millions of them. These agencies work according to two modes. In the first one, they respond to a customer query by sending him a set of images. The customer pays for the images that he publishes. In the second mode, the customers are subscribers at the agencies which send their new photographs systematically to them, the mode of payment being the same one. This working method is that of the AFP or Reuters.

One of the concerns of the agencies is of course the digital rights management, and the fact that they are not unduly used by people or institutions while not having discharged the rights. Watermarking and indexing are two techniques planned to control image diffusion, either by seeking a watermark of property in the images, or by checking, using indexing techniques, that the image is not a fragment of an image of the agency base.
