With the development of artificial intelligence and digital culture in recent years

generative algorithms have begun to be used in all sectors of urban culture and creative design. Research was conducted in this paper on the inner logic of generative algorithms for modifying urban images and the practical problems traditional creative images have in terms of cost

uniformity and weak interactivity. Research has found that the new mode of creation is a joint effort by people and artificial intelligence. By multimodally re-encoding semantics

the above algorithms can create various kinds of cognitive maps that connect urban historical symbols with digital spaces and build an interactive dissemination ecosystem based on "value co-creation"

and this paper presents a new theoretical system and practical reference for urban image branding

spatial narrative design and the digitalisation of cultural and creative industries in the intelligence era.
