In this paper, a supervised enhancement method dedicated to underwater images is presented. It is well-known that the water alters the light propagation. Underwater images often present low contrast and luminosity. The aim of the proposed method is to correct the effects of the light propagation in the water. This method is based on the physical properties of the light. The originality of this processing is to work without any a priori information about the scene or about the water composition. Experiments show that this method increases the contrast and the color dynamic of underwater images while preserving a good color rendering. In addition, the analysis of the experimental results, conducts a relation between optical parameters and colorimetric attributes.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
