20.4. Edge-Adaptive Scaling Algorithm
The edge-adaptive scaling algorithm is almost identical to the polyphase algorithm. It has extensions to detect edges in the input video and uses a different set of scaling coefficients to generate output pixels that lie on detected edges.
In the edge-adaptive mode, each bank of scaling coefficients inside the IP core consists of the following two full coefficient sets:
- A set for pixels that do not lie on the edge—allows you to select a coefficient set with a softer frequency response for the non-edge pixels.
- A set for pixels that lie on the edges—allows you to select a coefficient set with a harsher frequency response for the edge pixels.
These options potentially offer you a more favorable trade-off between blurring and ringing around edges. The Scaler II requires you to select the option to load coefficients at run time to use the edge-adaptive mode; the IP core does not support fixed coefficients set at compile time.
Note: Intel recommends that you use Lanczos-2 coefficients for the non-edge coefficients and Lanczos-3 or Lanczos-4 for the edge coefficients.
