Abstract

A curve alignment method and apparatus are provided. In the method, data obtained by at least one equipment analyzing a test sample is retrieved to generate test curves. In response to an alignment operation of directing a first point around a first curve to a second point around a second curve among the test curves, a correspondence between features corresponding to the first and second points is recorded, and correspondences of alignment operations are collected as feature data. Data obtained by the equipment analyzing a current sample is retrieved to generate current curves, and a third point matching the first feature on a third curve and a fourth point matching the second feature on a fourth curve are searched according to the correspondences. At least one of the third curve and the fourth curve is adjusted to align the third point with the fourth point.
