I am compiling the examples on a Ubuntu machine (8.04) and every time i Interface with my webcam the image is captured correctly and the texture is created and displayed, yet no markers are ever found. When I create a pgm from my webcam and run the software using camera_image_single_frame.c it all works fine. I cannot seem to find the problem with my live images. It seems they are not being processed correctly.
I initialized artags with init_artag(cam_width,cam_height,3) and i am processing it with artag_find_objects(cam_image,1). If anyone has any ideas what is going wrong please enlighten me.
