Table 3.

Comparison of the two different ECC pipelines according to the four comparison criteria stated earlier, where score is any value from [1, 2, 3] with “1” and “3” indicating the worst and best cases. The number N in the left column indicates the number of samples collected for the evaluation of each criterion.
