Examples of time series filtered using the TFCE algorithm with different combinations of parameters. A larger E weighs more the components of the original signal with longer temporal extent (e), defined as the time interval where the signal is consistently above a predefined minimum. Larger H, conversely, weighs more the highest components of the signal in terms of intensity (h). Note that the TFCE values here are normalized for visualization purposes only.

Perimetry, the mapping of the sensitivity of different visual field locations, is an essential procedure in ophthalmology. Unfortunately, standard automated perimetry (SAP), suffers from some practical issues: it can be tedious, requires manual feedback and a high level of patient compliance. These factors limit the effectiveness of perimetry in so...

... e is the extent (temporal duration) and h is the height (spatial magnitude) of D(t) at a given 98 point in time t (see Figure 2 for examples). This integral is implemented as a discrete sum using values (blue signals) enhance the clusters with higher peaks and suppress the lower ones ( Figure 2). ...

The measurement of retinal sensitivity at different visual field locations–perimetry–is a fundamental procedure in ophthalmology. The most common technique for this scope, the Standard Automated Perimetry, suffers from several issues that make it less suitable to test specific clinical populations: it can be tedious, it requires motor manual feedba...
