Type: SystemString
The file name of the classifier
thresholdDelta (Optional)
Type: SystemInt32
Threshold step in subsequent thresholds when extracting the component tree.
minArea (Optional)
Type: SystemSingle
The minimum area (% of image size) allowed for retreived ER’s.
maxArea (Optional)
Type: SystemSingle
The maximum area (% of image size) allowed for retreived ER’s.
minProbability (Optional)
Type: SystemSingle
The minimum probability P(er|character) allowed for retreived ER’s.
nonMaxSuppression (Optional)
Type: SystemBoolean
Whenever non-maximum suppression is done over the branch probabilities.
minProbabilityDiff (Optional)
Type: SystemSingle
