We present ordinal measures of association for image correspondence in the context of stereo. Linear correspondence measures like correlation and the sum of squared diier-ence between intensity distributions are known to be fragile. Ordinal measures which are based on relative ordering of intensity values in windows { rank permutations { have demonstrable robustness. By using distance metrics b...

We present ordinal measures of association for image correspondence in the context of stereo. Linear correspondence measures like correlation and the sum of squared difference between intensity distributions are known to be fragile. Ordinal measures which are based on relative ordering of intensity values in windows—rank permutations—have demonstrable robustness. By using distance metrics betwe...

PURPOSE To assess the relationship between quantitative measures of disc height and signal intensity with the Pfirrmann disc degeneration scoring system and to test the inter-rater reliability of the quantitative measures. METHODS Participants were 76 people who had recently recovered from their last episode of acute low back pain and underwent MRI scan on a single 3T machine. At all 380 lumb...

DInSAR data provide a powerful tool to recognize the Earth's surface where permanent deformations are concentrated and undergo strongest ground motion during an earthquake, i.e., defining epicentral area. We analyzed three recent seismic events in Apennines belt Italy related extensional contractional earthquakes documented that largest macroseismic intensity is recorded underwent vertical comp...
