Information about certain physical states of an examined object is encoded in the distribution of the fringe contrast in the metrological interference images of the object. Determining the contrast is one of the steps of converting the image into the distribution of the measured quantity in holographic fringe-contrast interferometry. In this paper, three methods of determining the fringe contrast in interference images containing speckle noise are compared. As the criterion for comparing the methods, the mean absolute error has been used. It turns out, in accordance with this criterium, the most effective method is the phase-shifting one.
