In this case, XGBoost and GLCM methods were used to extract features from LIBS spectrum and ablation image, respectively.
WebGLCM textural metrics produced 27 of the 46 significant single-predictor models, and at least one GLCM measure was included in five of the six best multiple-predictor models. A GLCM is created from a gray-scale image and represents the distribution of co-occurring values in a specified spatial relationship ( Haralick et al., 1973 , Hall-Beyer, 2024 , Hall … WebA co-occurrence matrix or co-occurrence distribution (also referred to as : gray-level co-occurrence matrices GLCMs) is a matrix that is defined over an image to be the …
