| 摘 要： | 现有分水岭算法对噪声敏感,易出现过度分割现象,导致图像分割边缘不明显。在传统分水岭算法基础上,通过形态学开闭重建来清除图像中的噪声点,并采用最小覆盖运算修改梯度图像,使得局部最小区域仅出现在标记位置,从而消除过分割现象。实验结果表明,与传统标记分水岭算法相比,用改进的算法对硬币图像和火焰图像进行处理,硬币轮廓识别率提高了56.67%,火焰目标分割效果提高了16.15%,取得了较好的图像处理效果。

| Abstract: | The existing watershed algorithm is sensitive to noise and prone to over segmentation, resulting in that the image segmentation edge is not obvious. Based on the traditional watershed algorithm, the noise points in the image are removed by morphological open close reconstruction, and the gradient image is modified by the minimum cover operation, so that the local minimum area only appears in the marked position, thereby eliminating the over segmentation phenomenon. The experimental results show that, compared with the traditional marking watershed algorithm, the recognition rate of coin contour is improved by 56.67%, and the segmentation effect of flame target is improved by 16.15% by using the algorithm designed in this paper to process the coin image and flame image. |
