A technique for halftoning video sequences is presented. First, an error metric is designed, incorporating psychophysical spatio-temporal contrast sensitivity data for the human visual system. An e cient strategy for producing halftone sequences that minimize the error is then developed. The technique is compared with video halftoning algorithms that do not consider the temporal aspect of the h...

Partial least squares (PLS) regression is a powerful and frequently applied technique in multivariate statistical process control when the process variables are highly correlated. Selection of the number of latent variables to build a representative model is an important issue. A metric frequently used by chemometricians for the determination of the number of latent variables is that of Wold’s ...

A least-squares model-based approach to digital halftoning is proposed. It exploits both a printer model and a model of visual perception. It produces a halftoned image that minimizes the squared error between the response of the visual model to the original image and the response of the printer and visual models to the halftoned image. For one-dimensional halftoning, where each column is proce...
