Video Capture with SDI Capture Card PE4 Active Silicon

lightmagic's picture

Hey there,

i have a problem getting a SDI Capture Card (Active Silicon PE4) to work with Quartz Composer. Driver is installed (there is only a CDA driver available, no Quicktime driver), in Catalyst (Media Server Software) it works. With the video input coming with Quartz Composer it shows only my iSight.

Is there any chance to embed the driver to Quartz Composer? Or is there any other video input patch around?

Thanks

Sweeping objects with body movement

Hi There!

I'm trying to wipe objects from the screen using body movement. The idea is that the people can sweep leaves from the screen moving their arms, so the objects can fly with a physical behavior revealing the image in the background.

My approach until now has been to isolate the person's figure adjusting contrast, and then creating an image that is only black or white, like a mask. Then my idea is to use this mask to repel the leave's positions.

I've tried the CV objects to do this but seems like there is no object for isolating blobs? face detecting works great, also point structures... but I couldn't find a way to detect a whole body in the CV tools.

I've also tried vade's optical flow and other objects with no better result...

Is there a way to build a particle cloud in a way that i can distribute its particle's positions in space using body movement? Is it possible to do this using a structure?

I've been able to distribute the objects of a structure in space but I don't know how to control each object's movement.

I think I'm gonna end controlling each object individually, in this case, anybody knows a repel algorithm that I can use?

Any help will be useful,

thanks!!

Hello Kineme community!

I am working now in a project that aims to use QC-Kineme motion tracking capabilities (CVTools, flow motion, etc) to build an interactive application that will be used as a presentation tool in fairs, events and live shows.

I just wanted to say hello, see you around!!
