... of spatial artifacts to form an overall quality assessment criteria for binary halftone videos. Video halftoning algorithm design can benefit from the temporal artifact evaluation criteria presented ... discussed above, it is desirable to reduce these temporal artifacts in the halftone videos. Therefore, per- ceptual quantitative measures for evaluating these artifacts are desirable. Quant...
