Study on application of digital image processing technique to analysis of sediment particle size
摘要
Abstract
The digital image processing technique-based analysis of sediment particle size is a new method developed in recent years.As the conventional watershed segmentation method directly acts on the gradient image under the impacts from the factors of image noise,exiguous edge and texture of object,its measuring accuracy is largely lowered.The watershed segmentation method is optimized herein through sign reconstruction and area merger,and then an improved algorithm is proposed.Based on the measured data and around relevant digital image processing techniques,a set of sediment imaging particle size analysis system is established on the basis of digital SLR camera and image processing software——Image J2x with the references of the image analysis equipment and methods in the other fields concerned.Whereafter,the particle size measurement is made on a same batch of sediment samples by image processing method,mechanical sieving method and laser analysis method respectively.The analysis of the measurement result shows that the digital image processing technique can be satisfactorily applied to the sediment particle size analysis.关键词
