Embodiment Construction
[0090] The present invention will be further described below in conjunction with the accompanying drawings. Specific embodiments of the present invention will be described below based on simulated hyperspectral image and real hyperspectral image data respectively.
[0091] 1. Simulated hyperspectral image experiment
[0092] In order to verify the feasibility and effectiveness of the model, the experiment is first carried out on the simulated hyperspectral image, and the specific steps are as follows:
[0093] A. Synthetic hyperspectral simulated oil spill images
[0094] First, extract oil endmembers and water endmembers from real hyperspectral oil spill images, and then synthesize a simulated hyperspectral image with a size of 200×200 and a number of bands of 258, in which the 100×100 part in the middle of the image is composed of oil endmembers , the other parts are composed of water endmembers, and finally adding noise with a certain signal-to-noise ratio (SNR, Signal Nois...
