Application of Textural Features in the Analysis of Breakstone Grading

Аннотация

Accuracy of breakstone grain-size analysis using digital images in the initial method and its modification based on algorithm proposed by D. Rubin is compared. A modification with averaging offeatures in all directions and the method with a classification feature represented by difference of intensity distribution functions of fragment projections are described. The results obtained using these methods in a series of tests on grading of five breakstone fractions measured in a certified laboratory. It is shown that the modified method by D. Rubin with averaging in all directions provides the highest accuracy.
