Perceptual fields reveal previously hidden dynamics of human visual motion sensitivity.

Motion sensitivity is a fundamental property of human vision. Although its neural correlates are normally only directly accessible with neurophysiological approaches, Neri (Neri P. J Neurosci 34: 8449-8491, 2014) proposed psychophysical reverse correlation to derive perceptual fields, revealing previously unseen dynamics of human motion detection. In this Neuro Forum, these key findings are dis...

Annotation of Human Motion Capture Data using Conditional Random Fields

Human motion classification is a challenging task since human motion lacks clear categorical structure. A reliable classifier can be used in anomaly detection, gait disease diagnosis, and content-based video querying. Moreoever, human motion classifier can be used in constructing motion capture database to eliminate manual labelling phase. Most of the proposed algorithms employ Hidden Markov Mo...

Motion microscopy for visualizing and quantifying small motions

Although the human visual system is remarkable at perceiving and interpreting motions, it has limited sensitivity, and we cannot see motions that are smaller than some threshold. Although difficult to visualize, tiny motions below this threshold are important and can reveal physical mechanisms, or be precursors to large motions in the case of mechanical failure. Here, we present a "motion micro...
