Filtration and Detection of Action Potentials in Optical Recordings
Result description
The main objective of this paper is to find useful part of signals in optical record of action potential. The averageing technique combined with continuous wavelet transformation (CWT) was employed to get better signal to noise ratio. CWT was used to split highly noised signal in separate repetitions. Signal to noise ratio was improved from SNR=2,6 to SNR=11,6. The signals were filtered and aligned in the time, baseline and amplitude. Than the dynamic time warpping algorithm was used to detect useful parts of signal.

Filtrace a detekce akčních potenciálu v optických záznamech
Czech description
Tento článek popisuje způsob vyhledávání užitečných částí v optickém záznamu akčních potenciálů. Kumulační techniky společně se spojitou vlnkovou transformací, byly využity ke získání lepšího odstupu signál/šum. Užitečné části signálu byly, po zarovnánív čase, amplitudě a základní linii, vyhledány pomoci algoritmu dynamické borcení časové osy.
