    This study introduces model-based error-diffusion for lenticular screening, improving digital halftoning quality by accounting for dot variations. A novel error-clipping method ensures stability and statistical independence for better lenticular image rendering.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Printing Technology

    Background:

    • Digital halftoning converts continuous-tone images to binary dots for printers.
    • High-resolution printing (1,200+ dpi) necessitates accounting for pixel-level dot variations and interactions.
    • Ignoring dot overlap in lenticular screening degrades image quality.

    Purpose of the Study:

    • To enhance lenticular screening quality in digital halftoning.
    • To address variations and interactions in printed dot size and shape.
    • To achieve statistical independence between component images in lenticular displays.

    Main Methods:

    • Utilizing model-based error-diffusion for lenticular screening.
    • Restricting error diffusion to pixels within the same component image.
