P-26: A New Objective Sharpness Evaluation Method Independent of Tone Reproducing Methods for Imaging Systems

A new objective sharpness evaluation method independent of tone reproducing methods has been developed using a cooperative human vision model which can simulate perceptual responses. The proposed method was applied to sharpness evaluation for continuous‐tone generalized knife‐edge images and their d...

Description
Summary:A new objective sharpness evaluation method independent of tone reproducing methods has been developed using a cooperative human vision model which can simulate perceptual responses. The proposed method was applied to sharpness evaluation for continuous‐tone generalized knife‐edge images and their digital halftone images. Consequently, the correlation coefficients between the objective and subjective evaluation values were over 0.97 irrespective of tone reproducing methods.
