A new minor update for cv.jit is available for download.
This version has been tested under both Max 4.6 and Max 5 in OSX and Windows. I haven't encountered any problem. However, since I was not able to reproduce the problem of cv.jit.sum not being recognized by Max 5, I would appreciate any confirmation that things are working (or not).
There is a single new object added to the collection, cv.jit.snake, which computes active contours, a point sequence that tries to fit itself to image contours.
The biggest change with this release (and for me it's quite a big one) is that cv.jit is now open source. The licensing terms were always vaguer than they should have been, but now the source is released under the LGPL. Source and project files are available from the usual download link.
Again, do not hesitate to let me know of any problem.
