RT Journal Article T1 Análisis petrográfico automático en Carbones de Capa T1 Automatic petrographic analysis of single seam coals A1 Catalina, Juan Carlos A1 Alarcón, D. A1 Prado, J. G. AB Anew system has been developed to improve the interlaboratory accuracy in maceral and reflectance analysis of single seam bituminous coals. It performs automatically both types of analysis, following the same steps as the manual method. Scanning, focusing and analysis are automatic; only preparation of coal samples and starting requires a human operator. The main and most novel Idea of this approach is to coordinate an expert system with an image processing system using both reflectance and morphological information. In this way the system tries to reproduce the analysis procedure followed by a human expert PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12231 UL http://hdl.handle.net/10272/12231 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
