bool ComponentLabeling	(	IplImage *	inputImage,
		IplImage *	maskImage,
		unsigned char	backgroundColor,
		Blob_vector &	blobs
	)

• FUNCIÓ: ComponentLabeling
• FUNCIONALITAT: Calcula els components binaris (blobs) d'una imatge amb connectivitat a 8
• PARÀMETRES:
  • inputImage: image to segment (pixel values different than blobColor are treated as background)
  • maskImage: if not NULL, all the pixels equal to 0 in mask are skipped in input image
  • backgroundColor: color of background (ignored pixels)
  • blobs: blob vector destination
• RESULTAT:
• RESTRICCIONS:
• AUTOR: rborras
• DATA DE CREACIÓ: 2008/04/21
• MODIFICACIÓ: Data. Autor. Descripció.
• NOTA: Algorithm based on "A linear-time component labeling algorithm using contour tracing technique", F.Chang et al
