Natural language evaluation system and method of relative color quality

摘要

Embodiments of the invention include a system for providing a natural language objective assessment of relative color quality between a reference and a source image. The system may include a color converter that receives a difference measurement between the reference image and source image and determines a color attribute change based on the difference measurement. The color attributes may include hue shift, saturation changes, and color variation, for instance. Additionally, a magnitude index facility determines a magnitude of the determined color attribute change. Further, a natural language selector maps the color attribute change and the magnitude of the change to natural language and generates a report of the color attribute change and the magnitude of the color attribute change. The output can then be communicated to a user in either text or audio form, or in both text and audio forms.
