  • Color image quality metric S-CIELAB and its application on halftone texture visibility

    Publication Year: 1997, Page(s):44 - 48
    Cited by:  Papers (26)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (399 KB)

    We describe experimental tests of a spatial extension to the CIELAB color metric for measuring color reproduction errors of digital images. The standard CIELAB /spl Delta/E metric is suitable for use on large uniform color targets, but not on images, because color sensitivity changes as a function of spatial pattern. The S-CIELAB extension includes a spatial processing step, prior to the CIELAB /s... View full abstract»

    Structured documents are represented as trees. The layout or presentation of a document is also often modeled as a computation over a tree. But these trees are not generally the same. For instance, L/sup A/T/sub E/X converts a structured document to the T/sub E/X formatting hierarchy of boxes and glue. In other words, presentation is a mapping between trees. Casting it as a formal tree transformat... View full abstract»
