Dredged sludge moisture prediction by textural analysis of the surface image

摘要

Texture analyses using the three dimensional color coordinates red (r), green (G), blue (B), and the gray (Y) channels co-occurrence matrix of sludge images were carried out for sludge moisture prediction. Four co-occurrence matrix textural features; information entropy, angular second moment, contrast, and correlation for image texture representation were tested to describe the moisture content variations of the drying sludge.
