Morphology

thresholding = threshold (semi-transparent) = threshold + ing

The word is formed regularly from the verb 'threshold' with '-ing', but the specialized technical sense is somewhat domain-specific.

Etymology

The word thresholding comes from threshold, which originally meant the 'door step' you walk over. So, think of drawing a line at that step: thresholding is setting that limit to decide if something is 'in' or 'out', for example whether a sound is heard or an object is seen.
