**4.1 Implementation of SGLCM for hepatic lesions using automated segmentation of the image block**

An automated segmentation scheme using a flexible image block size for automated liver tissue characterization is shown in Fig. 7.

Square image blocks of widths of 5, 8 and 10 pixels were used within the liver boundary. The purpose of automated segmentation with these various block sizes was for preliminary diagnosis of the entire liver, without requiring intervention by the user in identifying an ROI.
