Application of Hidden Markov Tree Model to On-line Detection of Surface Defects for Steel Strips
Open accessAbstract
摘要: 通过图像分割算法寻找由缺陷组成的可疑区域是热轧带钢表面缺陷在线检测与识别的关键。将热轧带钢表面图像分为“背景”和“缺陷”两大类,采用隐马尔可夫树(Hidden Markov tree,HMT)模型分别建模并实现多尺度缺陷分割。将不同类别的缺陷用同一个“缺陷模型”来表示,可以降低算法复杂度。HMT模型对带钢表面常见缺陷的分割正确率达到94.4%,分割错误率为18.8%。针对HMT模型得到的细尺度分割结果中分割错误率较高问题,引入基于环境的多尺度融合方法(Context-adaptive hidden Markov tree, CAHMT),将不同尺度的分割结果融合,大幅降低细尺度分割的分割错误率,达到3.7%。

Xu et al. decreased the detection false rate from 18.8% to 3.7% using the context-adaptive hidden Markov tree model (CAHMT).
“Further, Xu et al. [89] dramatically decreased the detection false rate from 18.8% to 3.7% by using the proposed context-adaptive hidden Markov tree model (CAHMT) based on an assertion that the correlation of wavelet coefficients of flat steel surface images at different scales satisfies Markov property.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
