Abstract
Materials and methods. The following principles of noisy signal filtration were used: linear smoothing forming the basic signal values, averaging by the period equal to mean pulse period, linear smoothing filtrating difference in videosignal and the obtained basic signal. The obtained difference is multiplied by the gain constant and added to the initial or the obtained basic signal. Conclusions. It was indicated that dynamic videoamplification, which does not apply filtration by the period equal to the mean value of pulse period, is of little use owing to artifacts available in the form of changes in brightness of lighting or relocation of the examined person. The offered algorithm differs from foreign analogs using dynamic amplification. The described mathematical methods for videosignal amplification are tested on videosignal of human forehead imaging.
