| 摘 要： | 超声测井图像低亮度低对比度区域的图像,采用常规直方图均衡算法进行图像增强无法很好的突出局部细节。为了解决这个问题,提出一种动态直方图均衡的图像算法对测井图像进行增强的算法。该算法的直方图是根据被均衡图像数据所在井段位置上下一个局部范围内进行统计,从而保证对每个深度的图像都尽可能均衡到最佳。实验结果证明,该算法较常规直方图均衡算法能更好的局部增强实际测井图像,对测井资料的处理具有很重要实际意义。

| Abstract: | In order to solve the limitations of the algorithm of ultrasound image enhancement based on histogram equalization,a method of ultrasound image contrast equalization is proposed based on the dynamic histogram equalization.The algorithm's histogram is statistics based on the image data to be equalization position of the upper and lower well section,which is ensure the best effect after the image of each depth is equalization.The experimental results show that the algorithm can be better effect for ultrasound... |
