1.Conventional/Discretized CONV/DISCRET_min, mean, max, std) CONV/DISCRET_peak 0.5 mL CONV/DISCRET_peak 1 mL CONV/DISCRET_CAS CONV/DISCRET_TLG (for TP, MN) CONV/DISCRET_RIM_(min, mean, sd, max) CONV/DISCRET_(Q1, Q2, Q3) 2. Histogram (HISTO): The histogram features consist of simple statistics that are asso- ciated with pixel values in images while the spatial patterns of the pixel values are not included. Entropy and energy are calculated.
