Constructor Detail

YehBokehEstimator

public YehBokehEstimator()

Construct with defaults: 5x5 blocks, variance threshold of 0.1, sharpness threshold of 0.5, lower bound of 0.3, upper bound of 0.7

YehBokehEstimator

public YehBokehEstimator(int nBlocksX,
                         int nBlocksY,
                         float varThreshold,
                         float sharpnessThreshold,
