Image quality assessment(IQA)model is designed to measure the image quality in consistent with subjective ratings by computational models.In this research,a valid no reference IQA(NR-IQA)model for color im-age sharpness assessment is proposed based on local color difference map in a color space.In the proposed model,the absolute color difference variation and relative color difference variation are combined to evaluate sharpness in YIQ color space(a color coordinate system for the development of the United States color television system).The differ-ence between sharpest and blurriest spot of an image is represented by the absolute color difference variation,and relative color difference variation expresses the variation in the image content.Extensive experiments are performed on five publicly available benchmark synthetic blur databases and two real blur databases,and the results prove that the proposed model work better than the other state-of-the-art and latest NR-IQA models for the prediction accura-cy on blurry images.Besides,the model maintains the lowest computational complexity.
