摘要：Low quality of underwater image due to color spread and absorption deals with the propagation of light wave length. In this paper we propose exponential equation approach to enhance underwater image color and maintaining color constancy. Exponential approach is conducted through two steps: first, determining the relation between the color intensity of an image underwater and the color intensity of an image in a certain depth; second, determining the coefficient of underwater image color absorption by using least square. The result of exponential approach is measured by using Peak Signal to Noise Ratio, yielding an average value of 19.18 and visually the result of the image color approximates its original color. Weconcluded that exponential approach can determine the color constancy level which in turns can enhance the underwater image just as its original color.
