**What it does**

This nonlinear filter, known as the top-hat operator in morphological mathematics (see Soille, ''Morphological Image Analysis''), is independent of the underlying baseline shape. It is able to detect an over brightness even if the environment is not uniform. The principle is based on the subtraction of a signal from its opening (erosion followed by a dilation). The size the structuring element (here a flat line) being conditioned by the width of the lineament (in our case the maximum width of a mass spectrometric peak) to be detected.
