A method (400) for identifying a feature in an image includes the steps of defining (410) a plurality of saliency values of an image or set of images over multiple parameters and calculating (414) an entropy value for each of the saliency values over substantially each of the multiple parameters. One or more peak entropy values are determined (430, 432) for the image or set of images based on the calculated entropy values. A feature of the image or set of images is identified (454), based on the weighted peak entropy value. An image transmission device, image transmission unit and image transmission system are also described. This provides a method and apparatus for extending scale definition to multiple parameters, thereby generalising the structures that can be identified, for example, to identify anisotropic regions. |
