title: Gradient-controlled iterative half-toning.
abstract: In digital half-toning there exists a general desire to adapt the properties of the half-toning algorithm to local properties of the input image. We show that consideration of the image gradient in an iterative convolution algorithm with a space-variant impulse response can be used to improve reproduction at high frequencies. Experiments demonstrate the properties and control of this algorithm.
