Methods

Create(int, int, int, double, double, int, double, double, int)

Creates MSER parameters

public static MSER Create(int delta = 5, int minArea = 60, int maxArea = 14400, double maxVariation = 0.25, double minDiversity = 0.2, int maxEvolution = 200, double areaThreshold = 1.01, double minMargin = 0.003, int edgeBlurSize = 5)

Parameters

delta int

delta, in the code, it compares (size_{i}-size_{i-delta})/size_{i-delta}

minArea int

prune the area which smaller than min_area

maxArea int

prune the area which bigger than max_area

maxVariation double

prune the area have simliar size to its children

minDiversity double

trace back to cut off mser with diversity < min_diversity

maxEvolution int

for color image, the evolution steps

areaThreshold double

the area threshold to cause re-initialize

minMargin double

ignore too small margin

edgeBlurSize int

the aperture size for edge blur
