A method to remove air bubbles in underwater video image is put forward. In bubble movement information of underwater video image,the traditional means of enhancement cannot achieve a satisfactory requirement,thus the improved independent component analysis algorithm is proposed in this paper to deal with it. The background and moving targets in image sequences are separated by the algorithm,and then the bubbles are separated from other moving targets and the air bubbles are removed in the gray domain. In the paper,the principle and the operation process of independent component analysis are introduced,and the simulation analysis was carried out on the experimental images.The results prove that this method can successfully from isolated bubbles in underwater image signal. the purpose of weakening the bubble field in underwater image is achieved by this method. Finally,using the optical flow method in the experimental results are analyzed,the results show that the method of removing image air bubble field water under the proposed is feasible.
