I don't remember whether you've said what software it is? But anyway, they probably use X as an intermediary because that means the problems of getting it working are all yours instead of theirs! :)
I did say. It is a program called nona, which is part of hugin, which stitches images together to form a panorama. I have 35000 km of images (this year alone, more the following years), with 8 images from 8 cameras each 10 meters. Each of those 8 are being stitched into a panorama image. As one might guess, any time that can be shaved off the processing is vital. As an aside, we found that if we implemented some other image cleaning/blurring (privacy - the images re delivered to the government who makes them generally available to the public) stuff using intel's Performance Primitives instead of using ImageMagick, we could reduce a processing time from 6 minutes down to 6 seconds. Doing the exact same things. In fact, we think that a sharpening step in the intel tools is providing better results. This was unexpected. We would have been happy cutting the time by 1/3, which is all we expected. I just wish we could do the same with Hugin. We can thread processing so we do 4 sets of images at a time, but we only get 8 image sets per minute. Hugin is a bit more complicated. But perhaps we need to see if we can help at all. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
