◆ AddFeature()
Add a feature to a feature set. If the feature set is already full, FALSE is returned to indicate that the feature could not be added to the set; otherwise, TRUE is returned.
- Parameters
-
FeatureSet | set of features to add Feature to |
Feature | feature to be added to FeatureSet |
- Returns
- TRUE if feature added to set, FALSE if set is already full.

|
Release the memory consumed by the specified feature.
- Parameters
-
Feature | feature to be deallocated. |
- Returns
- none

- History: Mon May 21 13:33:27 1990, DSJ, Created.
Definition at line 59 of file ocrfeatures.cpp.
◆ FreeFeatureSet()
Release the memory consumed by the specified feature set. This routine also frees the memory consumed by the features contained in the set.
- Parameters
-
FeatureSet | set of features to be freed |
- Returns
- none

◆ NewFeatureSet()
Allocate and return a new feature set large enough to hold the specified number of features.
- Parameters
-
NumFeatures | maximum # of features to be put in feature set |
- Returns
- New FEATURE_SET.

FEATURE_SET_STRUCT * FEATURE_SET
◆ ReadFeature()
Create a new feature of the specified type and read in the value of its parameters from File. The extra penalty for the feature is also computed by calling the appropriate function for the specified feature type. The correct text representation for a feature is a list of N floats where N is the number of parameters in the feature.
- Parameters
-
File | open text file to read feature from |
FeatureDesc | specifies type of feature to read from File |
- Returns
- New FEATURE read from File.
- Note
- Exceptions: ILLEGAL_FEATURE_PARAM if text file doesn't match expected format

◆ ReadFeatureSet()
Create a new feature set of the specified type and read in the features from File. The correct text representation for a feature set is an integer which specifies the number (N) of features in a set followed by a list of N feature descriptions.
- Parameters
-
File | open text file to read new feature set from |
FeatureDesc | specifies type of feature to read from File |
- Returns
- New feature set read from File.

◆ WriteFeature()
Appends a textual representation of Feature to str. This representation is simply a list of the N parameters of the feature, terminated with a newline. It is assumed that the ExtraPenalty field can be reconstructed from the parameters of the feature. It is also assumed that the feature type information is specified or assumed elsewhere.
- Parameters
-
Feature | feature to write out to str |
str | string to write Feature to |
- Returns
- none

◆ WriteFeatureSet()
Write a textual representation of FeatureSet to File. This representation is an integer specifying the number of features in the set, followed by a newline, followed by text representations for each feature in the set.
- Parameters
-
FeatureSet | feature set to write to File |
str | string to write Feature to |
- Returns
- none
