Computer Aided Decorative Art Design and Multimedia Dynamic Display Based on Deep Learning Model

With the change in consumers' consumption concepts, the traditional marine brand image lacks professionalism and diversity in the new media environment, which is not in line with the characteristics of new media information dissemination.The development of computer-aided design technology and multimedia technology broadens the ideas for marine brand image optimization.Therefore, this paper constructs a marine brand image perception model based on network text mining to understand the consumers' emotional perception of the corporate brand image from multiple aspects.The optimization of brand image is realized through an intelligent computer-aided design model.The experimental results show that the marine brand image perception model based on network text mining can effectively mine consumers' perceived emotions and recognition of the brand image.The intelligent optimization model of marine brand image perception based on visual communication can optimize the brand image according to the results of emotional analysis.The survey results show that consumers have a higher degree of recognition of the optimized brand image and deepen their cognition of corporate exclusivity, which improves the positive perceived emotion of the marine brand image.
