摘　　要：针对水下复杂环境情况,提出了一种快速实时检测水下运动目标的算法.在分析水下图像特性的基础上,对图像序列进行帧间差值运算得到差分图像,选择合适的阈值,对差分图像进行二值化和图像分割算法.结合差分图像中目标是由于待检测目标运动形成的特点,提出了衡量二值目标形状的线度指标的定义,可以描述目标的形状,从而实现快速实时检测水下运动目标.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.
