3.1. Shape parameters
The average and standard deviation values of all shape parameters
extracted from database images of the training set (190 regular
and 38 misshapen potatoes) are shown in Table 1. The results
revealed that the misshapen potatoes had a wide range of variation
for all shape parameters compared to the regular ones. This was
clear by looking at the values of standard deviation for misshapen
groups which were quite higher for all shape parameters.
