Kurtosis position is used as a local feature for measuring edges and reflecting the place of articulation recognition.
This parameter uses a 13 pixel spatial information filter (SI13) to measure edge impairments rather than Sobel filtering.

For tissue measured edge on, there is a higher OI in the neonatal pericardium than in the adult pericardium.
Measured edge on to the tissue, the collagen in neonatal pericardium is significantly more aligned (orientation index (OI) 0.78) than that in adult pericardium (OI 0.62).
The orientation of collagen measured edge on (alignment in plane) has been shown in bovine and ovine skin to be correlated with strength [ 15, 16].
Therefore if the OI measured edge on was only due to crimp, this would suggest that the neonatal pericardium, which is stronger, has less crimp and this would contradict the accepted knowledge of the influence of crimp.
The system spatial resolution was calculated as where s is the manufacturer-characterized spot size measured per the British Standard Method [ 17] and d ≈ 33 μm is the spatial detector blur estimated from a measured edge-spread function.
There was no significant difference for any of the implant types when measuring the edge-to-edge distance in the medial-to-lateral axis.
The lateral resolution was obtained by imaging a Ronchi grating with the center wavelength and measuring the edge resolution (10%-90%).
