WebChroma resampling consists of these operations: Downsample — Reduces the bandwidth required for transmission or storage of a signal. You can prevent aliasing by applying a lowpass filter to bandlimit the input signal. Upsample — Expands the bandwidth of the signal. This block performs interpolation to approximate the missing chrominance values.
