My research group has focused its efforts on the analysis, design,
and evaluation of error diffusion halftoning systems for grayscale
and color images.
For grayscale error diffusion, my group's contributions include:
For color error diffusion, my group's contributions include:
- frequency domain analysis,
- block error diffusion framework,
- quality assessment,
- joint optimization with interpolation,
- inverse halftoning, and
- halftone compression.
The above subjective quality assessment for halftone display on PC
monitors was conducted in a controlled laboratory setting and
Web-based framework, using the sRGB monitor standard.
- vector color diffusion framework, and
- quality assessment.
