Field Detail

extractRadius

public int extractRadius

Size of the feature used to detect the corners. Try 2

detectThreshold

public float detectThreshold

Minimum corner intensity required. Set to -Float.MAX_VALUE to detect every possible feature. Try 1. Feature intensity is computed using a Difference-of-Gaussian operation, which can have negative values.

maxFeaturesPerScale

public int maxFeaturesPerScale

Max detected features per scale. Disable with < 0. Tune, image dependent.

edgeThreshold

public double edgeThreshold

Threshold for edge filtering. Disable with a value <= 0. Try 5
