Depth-Stretch: Enhancing Depth Perception Without Depth
2017 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2017A simple and efficient method is presented to enhance the depth perception of an image. The approach termed Depth-Stretch (D-stretch) is a tone mapping operation that is applied to the shading component of the given image. Although re-rendering a scene under geometric transformations typically requires extracting the 3D model of the scene, we show that

Perception of depth in photographs
Journal of Audiovisual Media in Medicine, 1999In a world of computer-manipulated pictures easier than ever to achieve, many photographers and artists are called upon to combine images from various sources for illustrative purposes such as 'web pages', advertisements, public relations brochures, etc.

The Physics Teacher, 2017
In most disciplines, finding the distance from one object to the next is, at least in theory, a simple operation. Not so in astronomy. While the size of Earth itself was determined with a fair degree of accuracy in ancient times, the scale of the solar system wasn’t fully understood until just a few centuries ago, and the distances to even the closest ...

Attention and Depth Perception
Perception, 1986The Necker cube is a line drawing with two possible solutions in depth perception. The process of interpreting a two-dimensional line drawing as a three-dimensional object was investigated using the Necker cube. Attention was directed to a local feature of a briefly presented cube, ie an angle at a vertex.

VERTICAL DISPARITY IN DEPTH PERCEPTION*
Optometry and Vision Science, 1970ABSTRACT The apparent frontoparallcl plane (AFPP) is determined under three different conditions of vertical disparity using a two‐alternative forced‐choice experimental format. Representative data for one observer are given in which response to vertical disparity is found to lie in the range ...

We do not have direct, real-time visual access to the entities and events inside living human bodies. Despite the increasingly precise apparent access facilitated by medical-imaging technology, we still rely, finally, on representational and discursive tools in order to visualize and think about living organs, or microbes, or pathophysiological ...

Interactive Depth of Focus for Improved Depth Perception
2016The need to look into human body for better diagnosis, improved surgical planning and minimally invasive surgery led to breakthroughs in medical imaging. But, intra-operatively a surgeon needs to look at multi-modal imaging data on multiple displays and to fuse the multi-modal data in the context of the patient.
