摘要：

Dither signals may be added to coarsely quantized picture signals to mask undesirable contours. We show that a class of differential quantizers is equivalent to ordinary quantizers with respect to the design of dither signals. We give a design method for a number of deterministic and random dither waveforms and evaluate their visibility using a simple model of threshold vision. © 1969 The Bell System Technical Journal
