图像灰度分析技术应用——以明清与现代青花瓷纹样为例

Application of Image Grayscale Analysis Technology-Taking Ming,Qing,and Modern Blue and White Porcelain Patterns as Examples

青花瓷纹样因其单色的表现形式,纹样是通过颜料的浓淡变化进行控制的。人类约3/4的感光细胞是色盲的,因此,相比于色彩,人眼对于灰度变化更敏感,青花瓷纹样颜料的浓淡变化本质上是灰度变化,使用灰度变化来营造画面。不同时期的青花瓷纹样灰度变化受时代影响而发生改变,因此,以现代图像分析技术为手段,以古代和现代青花瓷纹样作为比较对象,对纹样的边缘线进行灰度检测,分析古代和现代青花瓷纹样灰度变化特征。

The pattern of blue and white porcelain is controlled by the change in color of the pigment due to its monochromatic expression.About three-quarters of human photosensitive cells are color blind.Therefore,compared to color,the human eye is more sensitive to grayscale changes.The color changes of blue and white porcelain pattern pigments are essentially grayscale changes,and grayscale changes are used to create the image.The grayscale changes of blue and white porcelain patterns in different periods are influenced by the times.Therefore,using modern image analysis techniques and comparing ancient and modern blue and white porcelain patterns,grayscale detection is performed on the edge lines of patterns to analyze the grayscale changes in ancient and modern blue and white porcelain patterns.
