CharacterFeatures
Description
This structure contains information about character features, which will be used during usage Optical Character Recognition filters. It is used to create an OcrSvmModel.
Structure fields and default values (if defined) are described below:
- bool Pixels - Grayscale level of all pixels.
- bool NormalizedPixels - Levels should be normalized to maximum 1.0
- bool Convexity - Character convexity value
- bool Circularity - Character circularity
- bool NumberOfHoles - Number of holes
- bool AspectRatio - Aspect ratio of character
- bool Width - Maximal width of character
- bool Height - Maximal height of character
- bool AreaRatio - Area of character
- bool DiameterRatio - Normalized diameter of the character
- bool Elongation - Aspect ratio of bounding ellipses diameters
- bool Orientation - Orientation of character.
- bool HorizontalProjection - Character projection on the Y axis.
- bool VerticalProjection - Character projection on the X axis.
- bool HoughCircles - Circles found in characteristic points of letters.
- bool Zoning4x4 - Downsampled to 4x4 pixels image of character.
- bool Moment_11 - M11 moment of character.
- bool Moment_02 - M02 moment of character.
- bool Moment_20 - M20 moment of character.
