Abstract: Processing element on a server performs a (wavelet) transform on an image held by the server storage device. Client user continuously specifies a foveal region with user input means dynamically, in realtime, which request is converted to a request for wavelet coefficients on the server corresponding to the foveal region. As the server continuously sends requested coefficients, client inverse wavelet transform means performs inverse wavelet transform on coefficients and continuously updates the image on the display.

Abstract: An apparatus provides a realtime visualization of at least one original image that is forwarded by a server. The apparatus includes a communication arrangement which receives the original image from the server, and a memory device which can store particular data for the original image using a data structure. The data structure may have particular data which is in a form that is independent from the original image provided by the server. The client also includes a user input device which provides at least one visualization command from at least one user. A processing arrangement of the client apparatus generates data corresponding to a multifoveated image using the visualization command and possibly the particular data, the data corresponding to a current multifoveated image.

Abstract: A client apparatus which enables a realtime visualization of at least one image. The client apparatus includes a storage device which stores first data corresponding to a multifoveated representation of an original image, and a user input device which providing second data corresponding to at least one visualization command of at least one user. In addition, the client apparatus includes a processing arrangement which generates third data corresponding to a multifoveated image using the first data, the second data and a foveation operator.
