A schematic exemplification of how a grey level co-occurrence matrix is being created in the horizontal direction. Schematic illustration of the pre-analysis processing of images. The original image (a) has been transformed to a binary image (b) for the separation of the pulmonary parenchyma from the background (step 1). The background of the image is set to NaN (c) (step 2) and the image is ready for the estimation of the GLCMs in the horizontal direction (step 3). The red and green rectangles indicate how often the pixel pairs (0, 0) and (1, 1) are occurring in the image respectively
