The invention discloses an intelligent
creative design system based on a
diffusion model. The
system comprises sketch generation, sketch optimization, style migration and high-quality rendering. According to the method, the design efficiency and innovativeness are improved through an intelligent technology, and meanwhile, the personalized requirements of users are met. According to the
system, firstly, diversified design sketches are generated through a
diffusion model, an initial sketch is generated through
Gaussian noise step-by-step iteration, and keywords or style labels input by a user are introduced in combination with a conditional
diffusion model so as to control the generation direction; performing
feature extraction on the sketch by using a
convolutional neural network, and optimizing lines and structures of the sketch through a multi-layer
perceptron; then, in combination with a style migration technology, migrating an artistic style specified by a user into the sketch, and meanwhile, introducing an attention mechanism to ensure local detail consistency of style migration; and finally, performing high-quality rendering on the design by using a GAN, optimizing detail performance through adversarial training of a
discriminator and a generator, and improving the
image resolution by using a super-resolution technology.
