final case class Blobs2D(in: D, width: I, height: I, thresh: D = 0.3, pad: I = 0) extends MultiOut[Any] with Product with Serializable
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
