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,
                         float lowerBound,
                         float upperBound)

Construct with the given parameters.

Parameters:

nBlocksX - number of blocks in the x-direction

nBlocksY - number of blocks in the y-direction

varThreshold - threshold for the variance

sharpnessThreshold - threshold for the sharpness

lowerBound - lower bound on Qbokeh for bokeh to be detected

upperBound - upper bound on Qbokeh for bokeh to be detected
