摘　　要：当前视觉图像缩放效果评价模型仅采用硬性评价指标,缺少对模糊参数评价的灵活性,存在敏感性低、评价结果主客观一致性差和评价代价高的问题,故设计视觉图像缩放效果评价的心理感知模型。通过提取图像底层亮度、颜色及方向等视觉感知特征完成特征采集;再通过视觉图像缩放评价参数分析计算质量参数和变形度参数,得出缩放视觉图像的形变量和变形区域,利用特征和相关参数构建心理感知模型,以实现视觉图像缩放效果评价。该实验结果表明,设计模型评价代价较低、敏感性较高、评价结果的主观一致性较好。The current visual image zooming effect evaluation models only uses rigid evaluation indicators,lacking the flexibility of fuzzy parameter evaluation,and it also has the problems of low sensitivity,poor subjective and objective consistency of evaluation results,and high evaluation cost.Therefore,a psychological perception model for visual image zooming effect evaluation is designed.The feature acquisition is completed by extracting the visual perception features such as the brightness,color and direction of the image bottom layer.Then,the quality parameters and deformation parameters are calculated through the analysis of visual image zooming evaluation parameters,and the shape variables and deformation areas of the scaled visual image are obtained.The psychological perception evaluation model is constructed using features and related parameters to achieve the evaluation of visual image zooming effect.The experiment results show that the proposed method has lower evaluation cost,higher sensitivity and better subjective consistency of evaluation results.
