Blob Detection

I would like someone to process a black and white BufferedImage. I would like all the pixels of the blobs to be numbered seperately i.e. all pixels in region 1 have pixel value 1, etc. It would be good if the code ignored regions of a certain specified width x height and changed those pixel values to a certain value e.g. 0 The code needs to be written preferably in Java taking the parameter of a bufferedimage and outputting the new numbered bufferedimage. It would also be good if each region's co-ordinates were output too, or even each region stored as a new image. This has been advertised here as our usual programmer is not available at the moment. Please ask if you have any question and if you would like more information.
