Comparison of Scaler Kernels in y4mscaler
Frequency Response

Here are the resulting scaled frames, which were measured to create the frequency response graphs on the previous page.

Note that your monitor itself may interact with these images, producing moire patterns and other aliasing effects. For the most accurate results, view on a large high physical-resolution screen, which is set to low pixel resolution (i.e. big pixels on a high dot-pitch CRT). This chart is probably useless when viewed on an LCD monitor.
