提出了一种针对水下复杂环境的水下运动目标实时检测算法。在详细分析水下图像特征的基础上，对图像序列进行帧间相减，得到差分图像。选择合适的阈值，得到差分图像的二值化图像。完成对二值图像的分割。基于差分图像中的目标通过运动形成，给出了线性电平的定义。对目标的形状进行了有效的表征。因此，实现了对水下运动目标的实时检测。
An algorithm of real time detecting underwater moving targets was presented against underwater complex environment.The difference image was obtained by subtraction between frames in image series based on analyzing in detail characteristic of underwater images.The appropriate threshold was selected and the binary image of the difference image was obtained.The image segmentation was completed to the binary image.A definition of linear level was given based on targets in the difference image were formed by moving.The shape of targets was characterized effectively.Therefore,real time detecting underwater moving targets was implemented.
