Abstract
Edge information of an input digital image is obtained. Digital image data corresponding to the input digital image is transmitted to a receiver. The edge information is also transmitted to the receiver. An output digital image is obtained at the receiver by processing the digital image data received at the receiver using the edge information received at the receiver. In this way, because the edge information is transmitted separately, as side information, and does not have to be obtained at the receiver, the computational complexity requires of the receiver is low. This enables for example real-time edge-adaptive interpolation to be carried out at the receiver.
