Constructors

ERFilterNM1(string, int, float, float, float, bool, float)

Create an Extremal Region Filter for the 1st stage classifier of N&M algorithm

public ERFilterNM1(string classifierFileName, int thresholdDelta = 1, float minArea = 0.00025, float maxArea = 0.13, float minProbability = 0.4, bool nonMaxSuppression = true, float minProbabilityDiff = 0.1)

Parameters

classifierFileName string

The file name of the classifier

thresholdDelta int

Threshold step in subsequent thresholds when extracting the component tree.

minArea float

The minimum area (% of image size) allowed for retreived ER’s.

maxArea float

The maximum area (% of image size) allowed for retreived ER’s.

minProbability float

The minimum probability P(er|character) allowed for retreived ER’s.

nonMaxSuppression bool

Whenever non-maximum suppression is done over the branch probabilities.

minProbabilityDiff float

The minimum probability difference between local maxima and local minima ERs.
