The invention discloses a real ink mark driven
facsimile authentic method based on submerged space
diffusion, which comprises the following steps: firstly, collecting a target
facsimile image and a large number of real ink mark sample images, carrying out preprocessing operation on the images, and constructing a standardized
training set and a
test set; secondly, extracting a
contour diagram and a skeleton diagram from the target copy image, and mixing the
contour diagram and the skeleton diagram in a linear mode to generate a continuous structural feature map; constructing an ink mark
encoder, encoding the authentic mark sample, and extracting the pen and ink characteristics of the authentic ink mark sample; and finally, constructing a reinking network based on a latent space
diffusion model, and finally converting the optimized data representation into a
pixel image through a decoder to obtain a calligraphy image with natural ink marks and real strokes. The problems that in the prior art, copy images are inflexible in ink color and lack of natural ink color change are solved, meanwhile, stability of a
font skeleton and refinement of the
stroke of the to-be-restored area are guaranteed, and authentic transformation work is achieved.
