【摘要】：為客觀、有效地對(duì)古陶瓷進(jìn)行無損分類,提出了一種基于機(jī)器視覺古陶瓷無損分類識(shí)別方法。通過遍歷古陶瓷器型邊緣輪廓,獲取古陶瓷器型結(jié)構(gòu)細(xì)節(jié)特征,并在HSI空間下提取古陶瓷釉色多通道顏色直方圖特征。同時(shí),提取反映古陶瓷紋理多樣性的LBP紋飾特征�；谏鲜鎏卣�,采用機(jī)器學(xué)習(xí)方法實(shí)現(xiàn)古陶瓷器型結(jié)構(gòu)、釉色及其紋飾圖案的無損分類識(shí)別。結(jié)果表明:通過機(jī)器視覺可以有效地對(duì)古陶瓷進(jìn)行分類識(shí)別;在以16為曲率步長、9為LBP算子分塊數(shù)時(shí),分別提取古陶瓷結(jié)構(gòu),紋飾特征有較好的識(shí)別精度,其中,基于結(jié)構(gòu)與釉色融合特征相比單一特征具有更好的識(shí)別效果;當(dāng)古陶瓷發(fā)生結(jié)構(gòu)或紋飾上的小部分缺損時(shí),該方法可以保持一定的魯棒性,當(dāng)信息丟失或缺損為5%時(shí),平均識(shí)別率依舊可達(dá)85%以上,可期望實(shí)現(xiàn)古陶瓷科技鑒定中的良好應(yīng)用。
[Abstract]:In order to classify ancient ceramics objectively and effectively, a new method based on machine vision was proposed. By traversing the edge contours of ancient ceramics, the structural details of ancient ceramics were obtained. The multi-channel color histogram features of ancient ceramic glaze were extracted in HSI space. At the same time, LBP decorative features reflecting the texture diversity of ancient ceramics were extracted, based on the above features. The machine learning method is used to realize the nondestructive classification and recognition of the structure, glaze and patterns of ancient ceramics. The results show that the classification and recognition of ancient ceramics can be effectively carried out by machine vision. With 16 as the curvature step size and 9 as the LBP operator block number, the ancient ceramic structures are extracted, and the decorative features have good recognition accuracy. Compared with single feature, the recognition effect based on structure and glaze fusion is better than that of single feature. The method can maintain a certain robustness when a small part of the defect on the structure or decoration occurs. When the information is lost or the defect is 5, the average recognition rate can still reach more than 85%. It can be expected to realize the good application in the scientific and technological appraisal of ancient ceramics.
