An automated method for detecting low-speed streaks in laser-induced fluorescence (LIF) images of turbulent boundary layers is described. The method, based on the identification and characterization of local maxima in intensity educes all the low-speed streaks that can be visually identified in the LIF images. The proposed algorithm seems robust and can yield reliable information on the statistical characteristics of the streaks.
