I drew the box in the middle of the picture, despite what actual photo is (75% width / height of the original photo), 2 out of 15 times of trial, I get passed.

Thanks! I am looking into this space for a while for my personal project. but 1m~3m distance is too small to my application. Do you know if this is plausible for direct sunlight and anyway to improve the distance?

the tech is around, but at very high price (a normal pointing laser costs 2k~3k, a proper lidar costs 30k to 70k). I think that is what the parent comment means "very unlikely".

I don't like the negativity associated with "first world" problem. The "first world" problems are very much real. If you believe that the rest of the world will catch up eventually with the "first world", they will have these "first world"

shamelessly plug: libccv supports REST-ful API in 0.4 version, it is open-source, and free: http://libccv.org/doc/doc-http/ . Trained pedestrian / car / face detectors are included.

Not growing is, in itself, a failure. Live Messenger had a chance to become what is SNS today at its time. But several missteps followed and a year ago, it closed its web existence (to Wordpress), and now this.

It would be most interesting to see a postmortem about why Live Messenger failed. As I can recall, it is a compelling product against AOL and Yahoo! IM. It is also competitive globally (well, I mean the U.S. and China). It has a competitive

Also it depends on the color, for blue, 8 bits may be sufficient, but definitely not green.

You are falling into the trap. Intellectual inventions simply shouldn't have full property right.

I admire their work, http://libccv.org/post/call-for-a-new-lightweight-c-based-co... Their documentation is very nice, and back then when I implementing linear MSER for OpenCV, I learned a lot from their semilinear MSER implementation. Bu

Personally, I am a little frustrated by OpenCV's move to C++ interface. Yes, it looks like a high-level language by mimicking Matlab style. But at the end of the day, the implementation uses many advanced C++ features, and ignored one thing

IP is protecting its usage (real world applications, ideally, with assessed damages), rather than the implementation. The analogy is: bulb is patented, but the patent shouldn't cover the bulb factory as well. You can pay for the damage, or

Yes, it is BSD 3-clause license. Added a link in front-page. As of GSL, I am not a guru on licensing, AFAIK, dynamic linking is a gray area and you can compile ccv without GSL dependency.

At minimal, it should be able to build without any dependencies (drop the code into your XCode project, and it will run). But to use command line tools in ./bin, you need libjpeg and libpng indeed. libgsl and liblinear are required for all

It is face detection (outline faces from images), not face recognition (tell whom the face belongs to). To train your own face detector, follow instructions here: http://libccv.org/doc/doc-bbf/#how-to-train-my-own-detector
