Morphology
The phrase is directly compositional: 'threshold' (a point/level) + 'operation' (a defined procedure) yields a procedure that uses a cutoff or decision level. Although used in technical contexts, a B1 learner who knows both constituent meanings can infer it denotes an operation applying a threshold.
Etymology
Threshold operation uses the image of a doorway: a threshold is the step at a door and an operation is an action that controls what goes through. So a threshold operation is like a guard at that door who only lets values 'pass' if they reach a set 'limit', which is why it means checking values and giving a 'yes' or 'no' result.
