摘要:

针对桥梁蜂窝麻面图像经常存在光照不均、多背景并存的干扰问题,提出了基于HSI颜色空间与灰度波动相结合的复杂桥梁蜂窝麻面的图像分割算法。首先,绘制S分量灰度变化曲线;其次,搜索曲线所有潜在的波峰波谷,并求相邻波峰波谷的高度差;然后,基于灰度像素个数差分值的标准差筛选出部分高度差;最后,基于部分高度差的标准差搜索最佳阈值完成图像的阈值分割。实验结果表明,与二维OTSU法、Niblack法、二维Tsallis熵法等几种算法相比,该算法的分割效果和实时性更好。

Abstract:

As the voids and pits image of bridge often has uneven illumination and multi-background interference problems, an image segmentation algorithm for complex voids and pits of bridge was proposed based on HSI color space and gray fluctuation. Firstly, S-component gray curve was plotted and all the potential peaks and troughs of the curve were searched, then the height differences between adjacent peaks and thoughs were calculated. Secondly, partial height differences were selected based on the standard deviation of gray pixel difference value. Finally the threshold segmentation of image was finished by searching the best threshold based on the standard deviation of partial height differences. Experimental results show that the proposed algorithm has better segmentation effect and real-time performance than OTSU, Niblack and Tsallis entropy method.

Key words: color image, HSI space, gray fluctuation, height difference, standard deviation, image segmentation
