Teaser of Amplitude Modulated Line-Based Halftoning

AM line-based halftonings, using (a) a carrier amplitude equal to the peak signal amplitude (some rows overlap), and (b) a zero-energy (suppressed) carrier.

We present a new approach for line-based halftoning of images, where banks of waveforms are modulated by the gray levels of the rendered image. We present examples that employ sinusoidal and triangular waveforms, and highlight some applications,including stylized rendering, halftoning in line-based devices, and education.
