Quality and compressibility analysis of checkerboard-based digital halftoning algorithms
… bi-level images produced by checkerboard-based halftoning algorithms. The specific halftone methods of this study are those described by R.M. Case. The bi-level images are created using C/C++ implementations of these algorithms (Villarreal, 2001). Image quality is assessed using human surveys …

Estimating toner usage with laser electrophotographic printers, and object map generation from raster input image
… object map is utilized in the object-oriented halftoning approach, where different halftone screens and color maps are applied to different types of objects on the page in order to improve the overall printing quality. The OMGA generates object map from the raster input directly. It solves …

Laser scanner jitter characterization, page content analysis for optimal rendering, and understanding image graininess
… incorporates the idea of object-oriented halftoning, which applies different halftone screens to different regions of the page, to improve the overall print quality. In particular, smooth areas are halftoned with a low-frequency screen to provide more stable printing; whereas detail areas …

Black-box printer models and their applications
… test page can either be embedded in the halftoning algorithm, or used to predict the printed halftone image at the input to an algorithm being used to assess print quality. In our research, we examine the potential influence of a larger neighborhood (45?45) of the digital halftone image …

Clustered-dot periodic halftone screen design and ICC profile color table compression
… compression.</p> <p>Screening is a widely used halftoning method. As a consequence of the lower resolution of digital presses and printers, the number of printer-addressable dots or holes in each microcell may be too few to provide the requisite number of tone lev- els between paper white and …
