Abbreviations: GLCM, gray level co-occurrence matrix; GLDM, gGray level dependence matrix; GLSZM, gray level size zone matrix; GLRLM, gray level run length matrix; LoG, Laplacian of Gaussian.

Note:Filter “original” indicates no filter applied. For filter “LoG”, the value in brackets indicates the filter width used for the Gaussian kernel. For filter “wavelet”, the label in brackets indicates the filter (H, high-pass filter; L, low-pass filter) applied.
