Component_Ronda has nothing to do with ASSURF.swc
it is a FONT name that comes from Miniml components

Hey Eugene,

I’ve been having the same error as Andy when trying to use the ASSURF.swc in Flash CS4 which is:

- ReferenceError: Error #1065: Variable Component_Ronda is not defined.

I’ve found that this error occurs when a class file isn’t defined meaning no “public” or “internal” definition before “class”. After checking your files, all of them are defined correctly. But when inspecting the surf.swc that you used to make the ASSURF.swc, the files in that library are mostly not defined.

example:
- file AlchemyBlock.as

package cmodule.surf
{

class AlchemyBlock extends Object
{

function AlchemyBlock()
{
return;
}// end function

}
}

Flash CS4 throws an error when a class isn’t defined but Flash Builder doesn’t which makes this library only usable in Flash Builder. Is there a way to add the “public” to all those classes in surf.swc before building the ASSURF.swc so it can be used with Flash CS4?

Any help on this would be appreciated.

@Carsten

Did you get an answer from the Inventors of SURF? We would also like to use the SURF algorithm in a commercial project…

Hey Eugene
Thank you for sharing Your knowledge, great stuff!!!
I’m working on a commercial project were we want to use ASSurf. We have tried to get in touch with the guys behind http://www.vision.ee.ethz.ch/~surf/download.html to be sure that we can use the SURF algorithm, but no one returns our mails so far. Do You know if the patent is for real and if so who should I contact?

@Eugene
That did the trick, everything except the font is working, no biggy.
I was just wondering how can I go about finding the X and Y coordinates of the matches in your examples. I have managed to used the CameraMatchWithHomography and average the lines to get a middle X and Y coordinates but doing this with multiple images slows the program very much. I was wondering if there is a simple way to get X and Y co-ordinates from the DynamicMatchesWithSAveAndLoadRefs example. The program knows when the match is on the screen, I just need to find out where.

Thanks for your help,
Vlad

@Vlad Cazan i recommend u to use compiled SWC lib otherwise you should process your compiled project with TDSI tool every compilation to archive good FPS

Hello,
This is amazing work, thank you for releasing your source code. I just have one issue with the code. I have imported everything into Flash Builder and I got the DynamicMatchesWithSaveAndLoad to compile just fine except there are two issues. One is that the txt does not show up, the sliders and everything else do.I have tried to change the font file location and everything but no luck. Another issue is regarding the speed. When I run your compiled swf file I am getting about 28-30 FPS but when I compile using Flash Builder I can only seem to get 3-4 FPS. Do you know anything that could be related ???

Thanks for your help!
Vlad

Hi Eugene,

I just download ‘DynamicMatchesWithSaveAndLoadRefs’ from svn and try to export it from flash cs4 + FlashDevelop.

I was connect with your src and ASSURF.swc, just has one error message as below:
“ReferenceError: Error #1065: Variable Component_Ronda is not defined.”

do you have any idea what’s the error from ?
thanks for help.
