Design of psychological perception model for evaluating visual image zooming effect
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 psycholog-ical perception model for visual image zooming effect evaluation is designed.The feature acquisition is com-pleted 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 evalu-ation results.
