• Abstract: Why is it that we can recognize object identity and 3D shape from line drawings, even though they do not exist in the natural world? This paper hypothesizes that the human visual system perceives line drawings as if they were approximately realistic images. Moreover, the techniques of line drawing are chosen to accurately convey shape to a human observer. Several implications and variants of this hypothesis are explored.

  We believe accurate copying (strong perception) is the first step to visual o1. We introduce the concept of "slow perception" (SP), which guides the model to gradually perceive basic point-line combinations.

  Recent studies have shown that artificial neural networks (ANNs) can also be deceived by visual illusions. We show how visual illusions are encoded in diffusion models. We also show how to generate new unseen visual illusions in realistic images using text-to-image diffusion models.

  From an image of a person, we can easily infer the natural 3D pose and shape of the person even if ambiguity exists. We propose "Implicit 3D Human Mesh Recovery (ImpHMR)" that can implicitly imagine a person in 3D space at the feature-level.

  We study how sketches can be used as a weak label to detect salient objects present in an image. To accomplish this, we introduce a photo-to-sketch generation model that aims to generate sequential sketch coordinates corresponding to a given visual photo. Tests prove our hypothesis and delineate how our sketch-based saliency detection model gives a competitive performance compared to the state-of-the-art.

  We present DeepDrawing, a framework for converting roughly drawn sketches to realistic human body images. To encode complicated body shapes under various poses, we take a local-to-global approach. Our method produces more realistic images than the state-of-the-art sketch-to-image synthesis techniques.

We label training images as male, female, or non-binary, and train PIXIE to infer "gendered" 3D body shapes with a novel shape loss.

• The Role of Edges in Line Drawing Perception [15.24376124676205]
  It has often been conjectured that the effectiveness of line drawings can be explained by the similarity of edge images to line drawings. This paper presents several problems with explaining line drawing perception in terms of edges, and how the recently-proposed Realism Hypothesis of Hertzmann ( 2020) resolves these problems.
