Application of Image Processing to the Analysis of Gravel Shape in Jialing River
摘要
Abstract
The application of digital image processing technique to gravel shape analysis was introduced. The characteristics of shape factors(such as the maximum, intermediate & minimum diameters, the sphericity, and the degree of oblateness etc.) of gravel in the Jialing River was obtained using the image processing system. The variation of shape factors along the river channel was analyzed. It was found that the degree of oblateness decreases while the sphericity incerases from upstream to downstream. Classification based on c/b and b/a shows that the gravel tends to be disc or blade edge in the upstream and spheroid in the downstream.关键词
