An Algorithm for Particle Size Analysis of Gravel Image by Using Gray-Value Vibration Frequency

Article Preview

Abstract:

Due to it is very extensive usage in the application of production practice and scientific research in the present,Identifying particle size from digital image is an important technology.Up to now there have been some particle image size identification methods,Such as the improved watershed algorithm for adhesive rice image segmentation,Particle size analysis method based on spatial autocorrelation for deposit digital Image.But because the gravel image is a kind of special particle image,those methods are not very suitable for use in particle size analysis of gravel image.This paper puts forward a new particle image size identification method.Combing with the image threshold segmentation method,this new method is better able to extract gravel object from gravel image and rebuild the grid model of gravel size.
