Constructor & Destructor Documentation

EOCR() [1/2]

eVision.EOCR.EOCR

(

)

Constructs an OCR context.

By default, the Threshold property is set to 128.

EOCR() [2/2]

eVision.EOCR.EOCR

eVision.EOCR

other

)

Constructs an OCR context.

Parameters

other

Member Function Documentation

AddChar()

void eVision.EOCR.AddChar	(	int	originX,
		int	originY,
		int	endX,
		int	endY )

Add a character coordinates to the list.

Parameters

originX	Abscissa of the upper left corner of the bounding box of the character.
originY	Ordinate of the upper left corner of the bounding box of the character.
endX	Abscissa of the bottom right corner of the bounding box of the character.
endY	Ordinate of the bottom right corner of the bounding box of the character.

It is to use when you know the exact position of the characters to be recognized, to bypass the segmentation step, for efficiency or reliability purposes. To use this feature, simply specify the character positions by successive calls to AddChar. When this is done, the remainder of the OCR processing steps can take place. To empty the list of known characters, call EOCR.EmptyChars.

float eVision.EOCR.AverageFirstCharDistance

get

CharSpacing

int eVision.EOCR.CharSpacing

CompareAspectRatio

bool eVision.EOCR.CompareAspectRatio

getset

Flag indicating whether the character aspect ratio is used to compute the recognition score.

When true, the character aspect ratio is used to compute the recognition score.

CutLargeChars

bool eVision.EOCR.CutLargeChars

getset

Flag indicating whether the large chars cutting mode is used.

If true, candidate characters larger than MaxWidth are split into as many parts as required. If false, large characters are discarded. The segmentation parameters must be the same for both learning and recognition process.

LineSpacingMode

eVision.ELineSpacingMode eVision.EOCR.LineSpacingMode

getset

Line spacing mode to sort the character boxes into lines. Default mode is ELineSpacingMode.ELineSpacingMode_Overlap.

MatchingMode

eVision.EMatchingMode eVision.EOCR.MatchingMode

getset

Matching mode to use to compare characters to the template.

By default, the root-mean-square error method is used. These modes are meant to be used without thresholding, that is when one of the EOCRColor.EOCRColor_DarkOnLight and EOCRColor.EOCRColor_LightOnDark colors are used.

MaxCharHeight

int eVision.EOCR.MaxCharHeight

Maximum character height.

A character larger than the maximum width or higher than the maximum height is discarded. The segmentation parameters must be the same for both learning and recognition process.

MaxCharWidth

Maximum character width.

A character larger than the maximum width or higher than the maximum height is discarded. The segmentation parameters must be the same for both learning and recognition process.

MinCharHeight

int eVision.EOCR.MinCharHeight

getset

Minimum character height.

A character both narrower than the minimum width and lower than the minimum height is discarded by default (see EOCR.RemoveNarrowOrFlat). The segmentation parameters must be the same for both learning and recognition process.

MinCharWidth

int eVision.EOCR.MinCharWidth

getset

Minimum character width.

A character both narrower than the minimum width and lower than the minimum height is discarded by default (see EOCR.RemoveNarrowOrFlat). The segmentation parameters must be the same for both learning and recognition process.

NoiseArea

int eVision.EOCR.NoiseArea

getset

Noise area.

When a blob has an area smaller than this value, it is ignored. The segmentation parameters must be the same for both learning and recognition process.

NumChars

int eVision.EOCR.NumChars

int eVision.EOCR.NumPatterns

get

Current pattern width, as set at the last EOCR.NewFont or EOCR.Load operation.

RelativeSpacing

float eVision.EOCR.RelativeSpacing

getset

Relative spacing value.

This value is the ratio of the width of the spaces between characters and the character width. For example, characters 25 pixels wide separated by 10 pixels gaps correspond to a relative spacing of 10/25 = 0.4. The default value of this parameter is 0, corresponding to no spacing. This parameter is relevant only when the CutLargeChars mode is enabled. The segmentation parameters must be the same for both learning and recognition process.

RelativeThreshold

float eVision.EOCR.RelativeThreshold

getset

Relative threshold used for image segmentation.

The RelativeThreshold is the fraction of the image pixels that will be set below the threshold. Only used when the EOCR.Threshold property is set to EThresholdMode.EThresholdMode_Relative. The default value is 0.5.

getset

Flag indicating whether the characters are discarded when either dimension falls below the minimum value.

By default, no shifting is allowed (ShiftX = 0). The tolerance can be used in two ways: either each character is moved individually until the best match is found, or the set of characters is matched as a whole, until the best average error is reached. See EOCR.ShiftingMode.

ShiftYTolerance

uint eVision.EOCR.ShiftYTolerance

getset

Vertical translation tolerance around the nominal position when the character positions are explicitly specified.

By default, no shifting is allowed (ShiftY = 0). The tolerance can be used in two ways: either each character is moved individually until the best match is found, or the set of characters is matched as a whole, until the best average error is reached. See EOCR.ShiftingMode.

TextColor

eVision.EOCRColor eVision.EOCR.TextColor

getset

Text color.

The segmentation parameters must be the same for both learning and recognition process.

Threshold

int eVision.EOCR.Threshold
