 In 2001 instead of staring at the field at the game I turned around and watched the people watch the field. All I could see was a mass of people from all corners of the world, eyes lit up, gears turning in their heads. That, to me, is FIRST in action. - Jessica Boucher [more] |

Re: Image Threshold Produces Black Image
The problem I encountered was occurring with the output from vision assistant, I switched to using the colorImage->threshold function after getting the black screen there. The vision assistant seems to perform some extra steps on the jpg you give it to put it into the proper color space, which doesn't get done in the generated c code.
Perhaps I need to close the loop on this whole fiasco, it maybe that it originally worked fine doing the conversion in the generated code, but combination of bad particle analysis decomposition and from writing my binary image as a jpeg caused it to look 'broken'. But, throughout this, our vision assistant script has given us the expected result, while we were unable to get any results from the C++/c code (until switching color space).

Re: Image Threshold Produces Black Image
So, if I read this right, you're on your way to health. Yes? If so, then we'll just close this out until there's something new or you get a rockin' great tracker!
