| 摘 要： | 针对声呐图像受噪声干扰大，目标边界较模糊的特点，并结合传统直方图不变矩识别图像快速的优点，以及其不考虑灰度空间信息而易造成误识的缺点，将目标的形状阕子加入不变矩特征向量中，提出了一种对亮度和对比度变化不敏感，具有旋转和尺度不变性的改进的直方图不变矩．实验仿真结果表明，该方法能够快速、有效地识别水下目标．

| Abstract: | Considering the blurred boundary on the sonar image of target due to the heavy noise, this paper put forward an improved histogram invariant moments for the recognition of sonar image in conjunction with the shape factor from the traditional histogram invariant moments. This method is not sensitive to luminance and contrast. Mo- reover, the histogram invariant moments in this method feature invariant rotation and scale, not only preserving the recognition speed of the original method but avoiding the probability of wrong recognition due to the space informa- tion loss. Experimental results show that the improved method can recognize the underwater target quickly and effectively. |
