Motion is characterized by a series of positions an object traverses over time. An object presented sequentially at two positions, with a time delay between them, is sufficient for us to perceive ...

Binocular disparity is detected in the primary visual cortex by a process similar to calculation of local cross-correlation between left and right retinal images. As a consequence, correlation-based ...

Our ability to perceive the rich, three-dimensional nature of the world depends on stereopsis. It is a process by which the brain combines slightly different images from each eye (binocular disparity) ...

A goal in visual neuroscience is to reveal how the visual system reconstructs the three-dimensional (3D) representation of the world from two-dimensional retinal images. Although the importance of ...

A stereogram optical illusion is a fascinating visual puzzle that hides a 3D image within a 2D pattern. At first glance, it appears to be a random collection of repeating designs or colourful dots.
