Project Details


In multi mode coders, or when operating with a bank of coders, the coder selection is of high importance. Ideally, such a selector should choose the coder that minimizes the incurred perceptual distortion given the frame to be coded. Obviously, the incurred distortion can be achieved by running each coder, but such an approach may be far to complex. In this research carried out within the ARDOR project we address the problem of predicting the distortion performance of source coders conditioned on the current input frame, with complexity as a constraint.
