“…Therefore, it is necessary for us to research the method of colorimetric characterization of the digital camera for the ocean surface imaging. Up to now, different methods about the colorimetric characterization of digital cameras have been put forward in the world, such as polynomial formula [5][6][7][8][9][10][11][12][13][14][15] , artificial neural-network [16][17][18][19][20][21][22] , look-up-table [23] , and so on. Among them the method of polynomial formula has been widely used because the configuration of the polynomial formula model is rather simple, and its training procedure is most mature.…”
