Introduced by Tony Lindeberg in A time-causal and time-recursive analogue of the Gabor transform
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
The time-causal and time-recursive analogue of the Gabor transform provides a way to define a Gabor-like time-frequency analysis for real-time signals, for which the future cannot be accessed. This is achieved by choosing the temporal window function in a windowed Fourier transform as the time-causal limit kernel, which is a temporal kernel that is (i) time-causal, (ii) time-recursive and (iii) obeys temporal scale covariance.

Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
