LookingGlass: Generative Anamorphoses via Laplacian Pyramid Warping
Anamorphosis refers to a category of images that are intentionally distorted,
making them unrecognizable when viewed directly. Their true form only reveals
itself when seen from a specific viewpoint, which can be through some
catadioptric device like a mirror or a lens. While the construction of these
mathematical devices can be traced back to as early as the 17th century, they
are only interpretable when viewed from a specific vantage point and tend to
lose meaning when seen normally. In this paper, we revisit these famous optical
illusions with a generative twist. With the help of latent rectified flow
models, we propose a method to create anamorphic images that still retain a
valid interpretation when viewed directly. To this end, we introduce Laplacian
Pyramid Warping, a frequency-aware image warping technique key to generating
high-quality visuals. Our work extends Visual Anagrams (arXiv:2311.17919) to
latent space models and to a wider range of spatial transforms, enabling the
creation of novel generative perceptual illusions.

Latent rectified flow models and Laplacian Pyramid Warping are used to generate anamorphic images that maintain meaning when viewed directly.
