摘要
图像分割是数字图像处理中的一项关键技术。原油组分薄层色谱图的精确分割是后续各个组分定量计算与分析的基础。提出一种基于阈值和区域生长法相结合的分割方法,对预处理后的薄层色谱图进行分割。通过与单一阈值法的比较,结果表明该方法在提取目标的同时,能够有效地分离背景像素,提高分割精度。同时,该方法运算简单,能进一步提高分割的效率。
Image segmentation is a key technique of digital image processing. Analyses the crude oil group types and calculates the percentage of each group based on the accurate segmentation. Proposes a novel segmentation algorithm based on Threshold and Region Growing. Compared with the single threshold segmentation, the experiment indicated that the segmentation method presented has the advantage of extracting the target without any pixel of the background. In the meanwhile, with simple operation, the method can improve the efficiency of segmentation.
