Image processing based characterisation of coal cleat networks
2017年1月2日 In this paper, a feature extraction-based image processing method is introduced to identify and separate distinct cleat groups from 3D X-ray μCT images. Kernels (filters) representing explicit cleat features of coal are built and cleat separation is successfully achieved by convolutional operations on 3D coal images.
Image processing based characterisation of coal cleat networks
2017年1月2日 Characteristics of coal cleat networks have been extracted based on the image processing method presented in the Analysis chapter. Three coal samples have been analysed; the results are summarised in the following. The cleats captured in the images are mineralised, which makes them well visible in the scans.
