Abstract
U ovom diplomskom radu se obrađuje problem detekcije pulsa potpuno beskontaktnim metodama – naročito analizom videosnimke. Analiziraju se različiti pristupi problemu, njihove prednosti i mane te potencijalni načini za daljnja poboljšanja. Obrađuju se algoritmi iz domena bliskih centralnom problemu s posebnim naglaskom na primjenjivost postojećih i budućih algoritama za poboljšanje procesa mjerenja pulsa iz videosnimke osobe, poput načina pojačavanja videosnimke, detekcije lica te rukovanja šumom. Predstavlja se Python implementacija jednog od mogućih pristupa problemu. Algoritam na temelju promjene intenziteta boje kože kroz vrijeme raznim matematičkim postupcima konačno mjeri šum. Diskutiraju se rezultati predstavljene implementacije te moguća poboljšanja i poželjni budući radovi na algoritmu.
Abstract (english)
Central topic of this thesis is the analysis of the heartbeat detection methods using only contactless data collectors, namely cameras. Analysis of existing different approaches to the problem is provided, with the discussion of positive and negative sides of every approach. Potential future improvements are also discussed. There is an additional analysis of domains relevant to the central thesis with emphasis on provided added usability of the main pulse detection algorithm. Notable areas are face detection, video amplification and noise handling. Implementation of one such algorithm is provided in Python. Algorithm works by tracking changes in color intensity of the human skin over time. Various mathematical methods are applied to the measured signal in order to calculate the pulse rate. Implementation's results are provided and discussed, as well as possible future improvements to the algorithm.
