Abstract Wavelet transform has played an important role in the field of surveying data processing,as the noise can be eliminated effectively on the basis of wavelet decomposition and reconstruction. Currently, the research of wavelet denoising mainly focuses on the development of wavelet denoising methods,however, the validity assessment of wavelet denoising result should be indeed taken into account. Seeing that, a comparative study on validity assessment methods of wavelet denoising is down. The practical performance of existing validity assessment methods is obtained through a series of experiments.
Key words ：
