Selective Reflections: A light and sound installation using spectral tuning to play with depth perception

The project originated with the goal of creating an interactive light and sound installation for Highlight Delft, an innovative art and technology route. This involved incorporating holographic projection and spectral tuning to convey a specific perceptual phenomenon. The initial phase included extensive research into holographic projection,...

Using Chromostereopsis to Enhance Depth Perception in Photos by changing the Hue

The following paper explores the use of chromostereopsis for the purpose of enhancing the perceived depth in photos. Contrary to previous work, this is achieved by using a continuous depth map as input and creating a natural-looking photo with enhanced depth even when viewed without any type of three dimension technology. This is the first...

Using depth information to improve display interpretation: Evaluating the effect of increasing figure-ground separation with a Multi Layer Display on attitude indicator misinterpretation

In previous studies it was shown that both pilots and non-pilots sometimes make roll reversal errors (RREs) when the aircraft bank angle is presented on a moving horizon type attitude indicator. This incorrect input has been shown to be caused by a misinterpretation of the horizon symbol on such an attitude indicator. The figure-ground relation...

Self-­Supervised Learning for Visual Obstacle Avoidance

With a growing number of drones, the risk of collision with other air traffic or fixed obstacles increases. New safety measures are required to keep the operation of Unmanned Aerial Vehicles (UAVs) safe. One of these measures is the use of a Collision Avoidance System (CAS), a system that helps the drone autonomously detect and avoid obstacles....

How Do Neural Networks See Depth in Single Images?

Deep neural networks have lead to a breakthrough in depth estimation from single images. Recent work shows that the quality of these estimations is rapidly increasing. It is clear that neural networks can see depth in single images. However, to the best of our knowledge, no work currently exists that analyzes what these networks have learned. In...

Ways of Viewing Pictorial Plasticity

The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture...

Object-alignment performance in a head-mounted display versus a monitor

Perception and cognition of depth of field

A common way to present 3D materials to human observers nowadays is by stereoscopic displaying on 3D TVs or head-mounted displays such as the Oculus Rift. However, not everyone can see three-dimensional solid shape from stereoscopic viewing and the three-dimensional images remain two-dimensional pictures to them rather than solid shapes....

Interaction of depth probes and style of depiction

We study the effect of stylistic differences on the nature of pictorial spaces as they appear to an observer when looking into a picture. Four pictures chosen from diverse styles of depiction were studied by 2 different methods. Each method addresses pictorial depth but draws on a different bouquet of depth cues. We find that the depth...

Probing pictorial relief: From experimental design to surface reconstruction

The perception of pictorial surfaces has been studied quantitatively for more than 20 years. During this time, the “gauge figure method” has been shown to be a fast and intuitive method to quantify pictorial relief. In this method, observers have to adjust the attitude of a gauge figure such that it appears to lie flat on a surface in pictorial...

Pictorial depth probed through relative sizes

In the physical environment familiar size is an effective depth cue because the distance from the eye to an object equals the ratio of its physical size to its angular extent in the visual field. Such simple geometrical relations do not apply to pictorial space, since the eye itself is not in pictorial space, and consequently the notion ...

Measuring 3D point configurations in pictorial space

We propose a novel method to probe the depth structure of the pictorial space evoked by paintings. The method involves an exocentric pointing paradigm that allows one to find the slope of the geodesic connection between any pair of points in pictorial space. Since the locations of the points in the picture plane are known, this immediately...
