Demonstration of object recognition, scene classification, event classification, and expression recognition accuracy using different thresholds. a Accuracy of different constant thresholds. b Accuracy of different dynamic thresholds (i.e., percentage of the center pixel as threshold). All the results are generated considering ternary pattern in CENTRIST framework. Noteworthy, L (threshold used in LGP [16]), M (median threshold used in LAID [42]), S (SQRT of center pixel), and C (cube root of center pixel)
