“…However, these methods all correct the results of waveform data processing, neglecting the data's effective processing and deep mining during the processing process. Xia Yuhao et al [9] proposed a multispectral full-waveform lidar return decomposition method to deeply mine hyperspectral laser return waveform data in 2022. This method mainly detects and re-decompose the channels with outliers by checking neighbor distances and selecting specific wavelengths to compose a characteristic spectrum.…”
