CHAR_DESC ExtractBlobFeatures	(	const FEATURE_DEFS_STRUCT &	FeatureDefs,
		const DENORM &	denorm,
		TBLOB *	Blob
	)

Extract features from Blob by calling the feature extractor which is currently being used. This routine simply provides a high level interface to feature extraction. The caller can extract any type of features from a blob without understanding any lower level details.

Parameters:

FeatureDefs	definitions of feature types/extractors
denorm	Normalize/denormalize to access original image
Blob	blob to extract features from

Returns:

The character features extracted from Blob.
