Data processing techniques in transient electromagnetic (TEM) methods face numerous challenges, such as the problem of 3-D imaging and demand for new data arising from development small-loop TEM devices. We have developed an algorithm based on gradient features derived to address these challenges. found that normalising field responses under appropriate background conditions enables target. Numerical experiments conducted theoretical models validated feasibility this approach highlighted significance fields. further designed more complex achieved synthetic within seconds, demonstrating method's high efficiency applicability high-dimensional data. Subsequently, we applied challenging demonstrated its superior performance compared inversion method, which presents a novel This study demonstrates possesses characteristics wide applicability, suitable various dimensions types Furthermore, it holds promising potential assisting enhancement three-dimensional
