short int mr_elements_detector (  MrImage *  image, MrScore *  score, MrElementsDetector *  ed )

Extracts notes from an image where lines was previously detected and grouped in a partition.

void mr_elements_detector_clear (  MrElementsDetector *  ed  )

Destroy elements previously detected.

void mr_elements_detector_free (  void *  o  )

Destroy a notes detector

float mr_elements_detector_match (  MrElementsDetector *  model, unsigned int  posm, MrElementsDetector *  object, unsigned int  poo, float  scale_factor )

Match a graphic music element. This will be soon moved in another module.

MrElementsDetector* mr_elements_detector_new (   )

Creates a new notes detector

short int mr_elements_detector_origin (  MrElementsDetector *  ed, unsigned int  pos )

Translate elements in x so the left most element will have its x coordinate to 0.

unsigned int mr_elements_detector_size (  MrElementsDetector *  ed, unsigned int  pos )

Returns the number of graphics elements
