/**
- FUNCTION: CBlob
- FUNCTIONALITY: Constructor from an image. Fills an object with all the blobs in
the image
- PARAMETERS:
- source: image to extract the blobs from
- mask: optional mask to apply. The blobs will be extracted where the mask is
not 0. All the neighbouring blobs where the mask is 0 will be extern blobs
- threshold: threshold level to apply to the image before computing blobs
- findmoments: true to calculate the blob moments (slower) (needed to calculate elipses!)
- blackBlobs: true to search for black blobs in the binarization (it will join all extern white blobs).
false to search for white blobs in the binarization (it will join all extern black blobs).
- RESULT:
- object with all the blobs in the image. It throws an EXCEPCIO_CALCUL_BLOBS
if some error appears in the BlobAnalysis function
- RESTRICTIONS:
- AUTHOR: Ricard Borràs
- CREATION DATE: 25-05-2005.
