Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Gestalt Principles of Perception

Gestalt Principles of Perception

Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

Surface Tension and Surface Energy

Surface Tension and Surface Energy

When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Surface Tension of Fluid

Surface Tension of Fluid

Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.
Surface tension varies...

Perceptual Constancy

Perceptual Constancy

Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Subliminal Perception

Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Area of Science:

Visual perception
Computational neuroscience
Computer vision

Background:

Translucent objects like fruit and wax create complex images due to light reflection and transmission.
Previous research highlights the importance of perceived shape and shading in visual translucency perception.
The role of 3D shape inferred from surface gloss (shape from specular highlights) in translucency perception remains less understood.

Purpose of the Study:

To investigate how interactions between specular and non-specular image properties, derived from different 3D shape cues, influence the perception of translucency.
To develop and validate a computational model that predicts perceived translucency based on image features.

Main Methods:

Experiments were conducted to examine the influence of incongruent 3D shape information in specular and non-specular image components on perceived translucency.
A novel computational model was developed using measurable image features related to shading and specular highlights.
Model performance was evaluated using 10-fold cross-validation.

Main Results:

Perceived translucency can be explained by the incongruence between 3D shape cues used for specular and non-specular image components.
The proposed computational model, based on shading relative to specular highlights, explained 59% of the variability in perceived translucency judgments.
The model outperformed alternative models relying on explicit subjective measures of perceived surface shape.

Conclusions:

The visual system infers translucency from the interplay of specular and non-specular shading in glossy, semi-opaque materials.
The developed computational model implicitly captures relevant geometric information for predicting observer judgments of translucency.
Understanding the integration of different visual cues is crucial for explaining the perception of material properties like translucency.
