“…The algorithms used to predict the IMF percentage of live animals were based on regression analysis (Whittaker et al ., 1992;Amin et al ., 1993;Newcom et al ., 2002;Li et al ., 2009); neural network (Brethour, 1994;Amin et al ., 1992;Harron and Dony, 2009;Li et al ., 2009) or support vector machine (Harron and Dony, 2009), among others. These algorithms were developed from textural RTU image features such as a histogram of pixel grey levels, Fourier-based (Amin et al ., 1997;Hassen et al ., 1999b;Newcom et al ., 2002;Harron and Dony, 2009).…”
