测井工程图的前景背景分割方法

A foreground and background segmentation algorithm for well logs

在测井工程图纸的矢量化过程中经常采用二值化的方法达到分割前景与背景的目的,但是目前许多陈旧图纸严重退化,经典的大津阈值法二值化分割测井工程图纸的前景与背景存在着不足,该文针对这一问题提出了一种有效的前景背景分割方法,该方法先对背景图像进行采样,再利用双3次内插法生成背景图像,实现退化图纸的前、背景分割,为进一步分析测井工程图纸提供了方便.

Usually binarization methods are applied during the vectorization process of well logs, but the classical OTSU method has limitations when segmenting the foreground and background of old degradative graphs. To solve this problem, this paper presents an effectual method. First the background image is sampled, and then, on the basis of bicubie interpolation algorithm, rebuild the background image to implement segmentation for better analyzing the well logs.
