SC680: Introduction to Digital Halftoning
This course will provide an introduction to the fundamental concepts of digital halftoning. Overview of the most successful digital halftoning algorithms will be given. We will discuss basic aspects of printer modeling and color as they pertain to digital halftoning, compression, watermarking, and descreening of digital halftones.
SC514: Introduction to Digital Halftoning
This course provides an introduction to the fundamental concepts of digital halftoning with an overview of the most successful digital halftoning algorithms. We discuss basic aspects of printer modeling and color as they pertain to digital halftoning, compression, watermarking, and descreening of digital halftones.
SC515: Advanced Concepts in Digital Halftoning
This course provides an in-depth look at advanced concepts of digital halftoning. Monochrome and color models for the rendering device and human visual system are presented, and model-based, iterative approaches to digital halftoning and application to model-based monochrome and color halftoning are discussed.
