Pretreatment to terahertz absorption curves by narrow undulation constraint and Its quick implementation suggested by convex hull

open access: yesScientific Reports, 2022
In this work, a method of pretreating THz absorption curve is proposed, which leads to minimal range in absorption, reserving necessary undulation of curve for identification by convolutional neural network. The kernel thought of proposed method is about
