◆ BlobMicroFeatures()
This routine extracts micro-features from the specified blob and returns a list of the micro-features. All micro-features are normalized according to the specified line statistics.
- Parameters
-
Blob | blob to extract micro-features from |
cn_denorm | control parameter to feature extractor |
- Returns
- List of micro-features extracted from the blob.

◆ ConvertToMicroFeatures()
Convert Outline to MicroFeatures
- Parameters
-
Outline | outline to extract micro-features from |
MicroFeatures | list of micro-features to add to |
- Returns
- List of micro-features with new features added to front.

◆ ExtractMicroFeature()
This routine computes the feature parameters which describe the micro-feature that starts and Start and ends at End. A new micro-feature is allocated, filled with the feature parameters, and returned. The routine assumes that Start and End are not the same point. If they are the same point, nullptr is returned, a warning message is printed, and the current outline is dumped to stdout.
- Parameters
-
Start | starting point of micro-feature |
End | ending point of micro-feature |
- Returns
- New micro-feature or nullptr if the feature was rejected.
