The Object Segmentation Algorithms Research in Petroleum Geological Drawing Based on Ohta Color Space
YI Jue-fei · Journal of Oil and Gas Technology · 2009
Many geological drawings were accumulated in oil exploration and development history, vectorization of these drawings was great significance. To meet the accurate requirements, the manual vectorization is made, but the work is arduous, with low efficiency.Automatic vectorization is used to improve the work efficiency, but it has high error rate, therefore error-checking work is arduous. For the fundamental work of automatic vectorization-object segmentation, it is proposed that two-object segmentation algorithms are used in this paper, one is based on the color histogram the other is based on the color table cluster. Efficiency and robustness of these two algorithms are studied through a digital experiment.
