Image library building in information hiding research

Aimed at the lack of the image library building standard in information hiding and correlative research, a method was proposed to build an image library based on the image visual complexity. Firstly, the computation model of the image complexity was defined with the Watson visual model. Based on the model the image visual complexity was obtained. The simulation experiment demonstrates that the result from this computation model is basically consistent with the subjective judgment. According to this scale of complexity, images with various complexity can be selected out from immerse images for experimental use.
