freeware http://www.iamas.ac.jp/~jovan02/cv/download.html			cv.jit is a collection of max/msp/jitter tools for computer vision applications. The goals of this project are to provide externals and abstractions to assist users in tasks such as image segmentation, shape and gesture recognition, motion tracking, etc. as well as to provide educational tools that outline the basics of computer vision techniques.

cv.jit.blobs.centroids	External		Find center of mass for each connected component.
cv.jit.blobs.centroids.draw	Abstraction		Visualize output of cv.jit.blobs.centroids.
cv.jit.blobs.color	Abstraction		Visualize output of cv.jit.label.
cv.jit.blobs.direction	External		Find direction each connected component points to.
cv.jit.blobs.direction.draw	Abstraction		Visualize output of cv.jit.blobs.direction.
cv.jit.blobs.elongation	External		Calculate elongation for each connected component.
cv.jit.blobs.elongation.draw	Abstraction		Visualize output of cv.jit.blobs.elongation.
cv.jit.blobs.moments	External		Calculate moments of inertia for each connected component.
cv.jit.blobs.orient.draw	Abstraction		Visualize output of cv.jit.blobs.orientation.
cv.jit.blobs.orientation	External		Measure angle of main axis for each connected component.
cv.jit.blobs.recon	External		Carry out pattern recognition on each connected components.
cv.jit.blobs.sort	External		Re-arrange labels so that each connected component keeps the same from frame to frame.
cv.jit.canny	External		Extract binary edges from a greyscale image.
cv.jit.cartopol	Abstraction		Treats the data in two matrices as cartesian coordinates and translates to polar data.
cv.jit.centroids	External		centroids are a very cheap and robust way of doing motion tracking.
cv.jit.centroids.draw	Abstraction		Visualize output of cv.jit.centroids.
cv.jit.changetype	Abstraction		Convert the type of a matrix without changing other attributes.
cv.jit.circularity	Abstraction		Estimates how compact a shape is.
cv.jit.close	External		"Close" is the opposite of "open", that is, a "dilate" followed by and "erode".
cv.jit.covariance	External		Computes the covariance matrix of a vector.
cv.jit.dilate	External		This will make shapes fatter and although it will make noise all the more noticeable
cv.jit.direction	Abstraction		Calculates the direction a shape points to.
