MECHANISMS FOR GENERATING TEMPORAL FILTERS IN THE
"... Temporal patterns of sensory information are important cues in behaviors ranging from spatial analyses to communication. Neural representations of the temporal structure of sensory signals include fluctuations in the discharge rate of neurons over time (peripheral nervous system) and the differentia ..."

Temporal Filtering of Disparity Measurements
"... The paper proposes a temporal filtering technique for the disparity measurements generated by area-based stereomatching algorithms. The technique improves temporal consistency of disparity measurements by reducing the matching errors due to the noise affecting the imaging system. Moreover, the techn ..."

Gaze-contingent temporal filtering of video
- IN: EYE TRACKING RESEARCH AND APPLICATIONS (ETRA
, 2006
"... We describe an algorithm for manipulating the temporal resolution of a video in real time, contingent upon the viewer’s direction of gaze. The purpose of this work is to study the effect that a controlled manipulation of the temporal frequency content in realworld scenes has on eye movements. We bui ..."

build on the work of Perry and Geisler [1998; 2002], who manipulate spatial resolution as a function of gaze direction, allowing them to mimic the resolution distribution of the human retina or to simulate the effect of various diseases (e.g. glaucoma). Our temporal filtering algorithm is similar
Spatio-temporal energy models for the Perception of Motion
- J. OPT. SOC. AM. A
, 1985
"... A motion sequence may be represented as a single pattern in x-y-t space; a velocity of motion corresponds to a three-dimensional orientation in this space. Motion sinformation can be extracted by a system that responds to the oriented spatiotemporal energy. We discuss a class of models for human mot ..."

motion mechanisms in which the first stage consists of linear filters that are oriented in space-time and tuned in spatial frequency. The outputs of quadrature pairs of such filters are squared and summed to give a measure of motion energy. These responses are then fed into an opponent stage. Energy
SPATIO-TEMPORAL FILTER FOR ROI VIDEO CODING
"... Reallocating resources within a video sequence to the regions-of-interest increases the perceived quality at limited bandwidths. In this paper we combine a spatial filter with a temporal filter, which are both codec and standard independent. This spatio-temporal filter removes resources from both th ..."

Quasi-periodic spatio-temporal filtering

"... Abstract—This paper presents the online estimation of temporal frequency to simultaneously detect and identify the quasiperiodic motion of an object. We introduce color to increase discriminative power of a reoccurring object and to provide robustness to appearance changes due to illumination change ..."
