Exploration of Art Digital Design Technology Guided by Visual Communication Elements

From the perspective of visual communication elements, this paper proposes a digital design composite model based on style migration, trying to explore and innovate art digital design technology. In the image recognition and style migration model, the attention mechanism is added on the basis of ResNet50 network model to enhance the image recognition effect, and on the basis of VGG19 deep convolutional network model and optimization algorithm to realize the image style migration technology and digital redesign. On the basis of the proposed style migration model, a graphic rendering model is further proposed by combining the GrabCut algorithm and the VGG16 neural network, so as to realize the local style migration of patterns. In the application analysis of the artistic digitization of Zhuang brocade lamps, for example, the total percentage of “very approved” and “more approved” in the assessment of the style migration effect is more than 30%, and the style migration effect is better. The average scores of the art design effect evaluation of layers, elements and color richness are 4.02, 4.15 and 4.31, which are all higher than 4 points, and the performance is good. It is also recognized by experts and ordinary respondents in the satisfaction evaluation of art design.
