Quality Evaluation of Halftone by Halftoning Algorithm-Based Adaptive Method

In order to evaluate the halftoning algorithms and the corresponding halftones,a criterion is necessary.A series of halftonig algorithm-based methods are proposed,which(adapt) to the special properties of haltftoning algorithms.An adaptive method is proposed to evaluate the halftoning algorithms and the corresponding halftones,which is based on the statistical features of the residual image between the original image and the corresponding halftone on the retinal of human eye.
