Image augmentation device and method

An image augmentation method, applied to an electronic device, wherein the electronic device comprises a storage and a processor, the storage is configured to store a diffusion model, and the image augmentation method comprises the following steps:

• inputting a noise image corresponding to an original image and semantic information and a text vector corresponding to the original image into the diffusion model to generate a generated image, wherein the generated image comprises a partial contour of the original image, and the semantic information comprises a plurality of semantic categories and a plurality of semantic ranges corresponding to the semantic categories;
• and
• compositing the generated image and a plurality of guide images to generate an augmented image, wherein the guide images are generated by segmenting the original image based on the semantic ranges.
