Life cycle inventory analysis of granite production from
The life cycle inventory analysis was addressed by following the guidelines specified by the ISO 14044 Functional unit The unit reference for estimating the inputs and outputs related to the granite production chain was defined as 1 m 2 of finished granite tiles with dimensions of 60 × 40 × 2 cm which are standard pieces applied in construction
Automatic classification of granite tiles through colour and
We discuss the development of an expert system for automatic classification of granite tiles We propose new approaches to granite classification based on combined colour and texture analysis We evaluate the performance of different visual descriptors and classifiers Combination of colour and texture features proves highly effective in discriminating granite
