pix_biquad

The pix_biquad object applies a time-based Infinite Impulse Response (IIR) filter to images, functioning similarly to the audio biquad~ object but for visual data. It processes incoming images (x(n)) to produce filtered output images (y(n)) based on a set of six filter coefficients (fb0, fb1, fb2, ff1, ff2, ff3). Users can also reset the filter's internal buffers with a set message.
