Abstract

This research aims to study the color distribution of ocean surface over Chinese surrounding sea areas in the CIELAB color space. We measure the spectral reflectance of the East China Sea, the South China Sea and the Philippine Sea by using an underwater vertical profile spectrometer. Based on the standard formula of 1931CIEXYZ tristimulus values, the tristimulus values of the ocean surface color of each sea area were calculated and the ocean surface color were reproduced. The octree color quantization was used to quantify the chromaticity values of each sea area and the main chroma value information distribution of ocean surface was obtained in the CIELAB uniform color space. The obtained results are encouraging in that the chroma information of the ocean surface show differences in different sea areas and have their own characteristics.
