Image Features Eztraction of Gas/liquid Two-Phase Flow in Horizontal Pipeline by GLCM and GLGCM

摘要：

Gray level co-occurrence matrix (GLCM) and the gray level-gradient co-occurrence matrix (GLGCM) were used to analyze gas/liquid flow images. Gas/liquid twophase flow experiments were practiced and high-speed images were captured. A set of textural features were extracted from the GLCM and GLGCM. Examples of experimental results confirm the effectiveness of several features among them. All of the effective textural features have a relation with the gas/liquid density ratio,but not relate to the superficial velocity of gas or liquid.
