Application of colour image analysis in coal petrology
article
The Olympus CUE-3 Colour Image Analysis System (CIAS) offers various processing and statistical functions for the analysis of two-dimensional images of a variety of materials, based on the colour characteristics and geometric properties of structural and textural elements. In this investigation the applicability of CIAS to coal petrology is described. Four high volatile bituminous coal samples from the Westphalian Coal Measures of well Kemperkoul-1 (The Netherlands) have been analysed using CIAS as well as conventional point count analysis. A statistical comparison of the results shows that CIAS is competitive to conventional coal petrological analysis. The reduction of processing time by 50% and the improvement of the repeatability suggests that CIAS deserves serious consideration as an efficient alternative to conventional maceral group analysis. © 1993.
