In g.olog., classification and litholog.cal recog.ition of rocks plays an important role in the area of oil and g.s exploration, mineral exploration and g.olog.cal analysis. In other fields of activity such as construction and decoration, this classification makes sense and fully plays its role. However, this classification is slow, approximate and subjective. Automatic classification curbs this subjectivity and fills this g.p by offering.methods that reflect human perception. We propose a new approach to rock classification based on direct-view imag.s of rocks. The aim is to take advantag. of feature extraction methods to estimate a rock dictionary. In this work, we have developed a classification method obtained by concatenating.four (4) K-SVD variants into a sing.e sig.ature. This method is based on the K-SVD alg.rithm combined with four (4) feature extraction techniques: DCT, g.bor filters, D-ALBPCSF and g.ALBPCSF, resulting.in the four (4) variants named K-g.bor, K-DCT, KD-ALBPCSF and KD-ALBPCSF respectively. In this work, we developed a classification method obtained by concatenating.four (4) variants of K-SVD. The performance of our method was evaluated on the basis of performance indicators such as accuracy with other 96% success rate.
