摘要
The amplitude of internal waves is an important parameter for the remote-sensing detection. However, there is no analytic method developed for the amplitude inversion of internal waves based on optical remote-sensing images. In this article, the deep-learning model is introduced to inverse the amplitude of internal waves based on a large number of optical remote-sensing images. The peak-to-peak distance and 15 types of texture characteristic parameters of images are computed, and the relationship between the amplitude of internal waves and the characteristic parameters of remote-sensing images are also investigated. In addition, based on the correlation difference between these parameters and the amplitude, three types of deeplearning model are established by selecting different parameters as input variables. Results show that the inverted amplitude of internal waves from our models shows good agreement with the in-situ data of internal waves, and the average errors between them are about 6.7%, 4.9%, and 3.6%, respectively, which indicates that the deep-learning model is effective for amplitude inversion of internal waves based on optical remote-sensing images.
