object detectionObject Detection (Composition by gtoledo3)
This composition shows an object detection routine that's enabled by using an offscreen texture to store color values. I was inspired to whip up this composition after looking at the title and initial picture of an article at Lighthouse3D...but I haven't read the article yet! It's informed by a bunch of stuff I've been doing with id'ing moving objects with openCL; a simple version, if you will. It was a challenge to myself to reproduce the setup from the picture and title before reading the article. Also, due credit of influence to Xiang Bai, and Jamie Shotton for having written good material on id-ing objects, that make this sort of ultra-obvious if you've read their work, as well as the earlier work of many others. It's also pretty darn apparent after doing any math involving normal calc, or coordinate masking, imo, so credit to whoever invented that, and stuff like the ...triangle :) Limited to 10.6 because of the employment of some interaction patches. Keep source texture and rendering destination square for this example. 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!! |
