The feature extraction workflow: (a) whole slide image acquisition; (b) cropping of image tiles with different sizes (i.e., 1024 × 1024, 512 × 512, 256 × 256) within nodule capsules areas; (c) RGB to 8-bit conversion using four strategies (i.e., 8b, 8bw, RED, EOSIN) and subsequent feature extraction using the histogram, GLCM and Helmholtz analysis; (d) binarization of 8-bit images and subsequent feature extraction (i.e., TC-ratio, fractal dimension).
