Blobs2D

A blob detection UGen. It is based on the meta-balls algorithm by Julien Gachadoat (http://www.v3ga.net/processing/BlobDetection/).

Currently, we output four channels: - 0 - numBlobs - flushes for each window one element with the number of blobs detected - 1 - bounds - quadruplets of xMin, xMax, yMin, yMax - for each blob - 2 - numVertices - the number of vertices (contour coordinates) for each blob - 3 - vertices - tuples of x and y for the vertices of each blob

in: the image(s) to analyse
width: the width of the image
height: the height of the image
thresh: the threshold for blob detection between zero and one
pad: size of "border" to put around input matrices. If greater than zero, a border of that size is created internally, filled with the threshold value
