Table 1 - Descriptive statistics of intramuscular fat (%) content observed by chemical analysis and predicted by image analysis (n=35); bias and mean percentage error (MPE) for the distinct color segmentation procedures.
Figure 1 - Original (A), background suppressed (B) and segmented (C) image from Biceps femoris muscle representative of the beef samples.
Figure  2  -  Decomposition  of  the  mean  square  deviation  (MSD)  for  intramuscular  fat  in  squared bias (SB), squared difference between standard deviations (SDSD) and  lack of correlation weighted by the standard deviations (LCS) from distinct col
Figure  3  -  Relationship  between  observed  (chemical  analysis)  and  predicted  (image  analysis)  values  of  intramuscular fat from distinct color segmentation procedures, and dispersion of the ordinary  residues according to the observed values
