Decorative picture carving dimpled grain generation system and method based on AI algorithm

The invention discloses a system and a method for generating decorative picture carving dimpled grains based on an AI (Artificial Intelligence) algorithm. The method comprises the following steps: firstly, carrying out local area context semantic association analysis on a reference decorative picture to obtain a sequence of context reference decorative picture image block semantic feature vectors, then, carrying out word granularity-based context semantic coding on demand preference text description to obtain a sequence of demand preference word granularity semantic feature vectors, and then, carrying out word granularity-based context semantic coding on demand preference text description to obtain a demand preference word granularity semantic feature vector sequence; performing cross-modal feature bidirectional interactive fusion processing on the sequences of the two vectors to obtain a sequence of reference decorative picture image block-demand word granularity interactive feature vectors; and performing t
