【摘要】 特征提取本质上就是利用一定的规则将高维样本数据转移到低维特征子空间中,有利于特征分类及提取的一类方法。对图像进行特征提取是定量化研究古陶瓷的基础性工作,为后续古陶瓷鉴别提供条件。本文以景德镇窑不同历史时期撇口碗图像为研究对象,对其器型轮廓特征提取进行了Matlab分析与实现。实验结果表明,不同时代撇口碗器型轮廓具有明显的时代特征,是区分不同时期撇口碗和研究撇口碗器型结构的关键性指标。更多还原

【Abstract】 The essence of feature extraction is which take original high-dimensional data samples to a lower dimensional proper subspace for easier classification.For image feature extraction is a basic work for the quantitative research of ancient ceramics,provide the conditions for the follow-up of ancient ceramics identification.In this paper,set images of bowls from Jingdezhen kiln in the different historial dynasty.As an example apply feature extraction to analysis the outline of shape by Matlab.The result shows that the outline of bowl in the different dynasty has distinct time-characteristics which is the key to distinguish bowls in different dynasty and to study the structure of bowls.更多还原
