Painterly depiction of material properties
Journal of Vision
|July 8, 2020
Summary
This study investigated how humans perceive materials in paintings. Results show that while people can consistently judge painted material attributes, their agreement varies by attribute and medium, suggesting a universal perception mechanism.
Area of Science:
- Visual perception
- Art and material science
- Human-computer interaction
Background:
- Painters excel at depicting materials and their attributes realistically.
- Artistic depictions can deviate from natural laws while maintaining perceptual realism.
- Large-scale studies on material perception in paintings are lacking.
Purpose of the Study:
- To investigate the perception of 15 different materials and 10 attributes (e.g., glossiness, hardness) in painted artworks.
- To assess human consistency and agreement in judging painted material properties.
- To explore whether material perception is independent of the depiction medium.
Main Methods:
- Utilized human annotations to identify material instances in paintings.
- Participants provided perceptual judgments on material attributes for 30 unique painted material segments.
- Employed principal component analysis to compare findings with studies on photographs and renderings.
Main Results:
- Participants demonstrated high consistency in judging painted material attributes.
- Inter-participant agreement varied depending on the specific material attribute being perceived.
- Material perception in paintings showed independence from the medium of depiction, aligning with prior research.
Conclusions:
- Human perception of material attributes in paintings is robust and consistent.
- Variability in agreement highlights attribute-specific perceptual nuances.
- Findings support a generalized model of material perception across different visual media.

In the study of beam mechanics, shear diagrams play a crucial role in understanding the distribution of shear forces along the length of a beam. Consider a beam AB that is supported at both ends and subjected to perpendicular loads.
First, a free-body diagram of the beam is drawn, representing all the external forces and internal reactions acting on the beam. One can calculate the reaction forces at each support by employing the equilibrium equations of force and moment. The vertical component...

47.8K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

The phase of a given substance depends on the pressure and temperature. Thus, plots of pressure versus temperature showing the phase in each region provide considerable insights into the thermal properties of substances. Such plots are known as phase diagrams. For instance, in the phase diagram for water (Figure 1), the solid curve boundaries between the phases indicate phase transitions (i.e., temperatures and pressures at which the phases coexist).

The pV diagram, which is a graph of pressure versus volume of the gas under study, is helpful in describing certain aspects of the substance. When the substance behaves like an ideal gas, the ideal gas equation describes the relationship between its pressure and volume. On a pV diagram, it is common to plot an isotherm, which is a curve showing p as a function of V with the number of molecules and the temperature fixed. Then, for an ideal gas, the product of the pressure of the gas and its...

15.9K
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

1.7K
The stress-strain relationship in ductile materials such as structural steel or aluminium is intricate and progresses through several stages. When a specimen is loaded, it initially exhibits a linear length increase, depicted by a steep straight line on the stress-strain diagram. It indicates the material is elastically deforming and will return to its original shape once unloaded. However, when a critical stress value is reached, plastic deformation begins. This stage sees substantial...
