Diffusion Illusions: Hiding Images in Plain Sight
ction, we have examples with two images. As the one on the top is rotated, the image changes! The one on the top is multiplied by the one on the bottom (pixelwise), simulating how light would be filtered through two transparent sheets with images printed on them.
In this project, we generate optical illusions and perform stenography using off-the-shelf diffusion models - all of which work in the physical world too! The one on the top is multiplied by the one on the bottom (pixelwise), simulating how light would be filtered through two transparent sheets with images printed on them. Flip IllusionsRotation OverlaysHidden Overlays Diffusion illusions are generated through an iterative process: we optimize the output images with gradient descent, starting from pure noise.
