Arch Linux

Description:

This includes avx2 instruction at compile time without runtime detection.
An older cpu without avx2 will refuse to work.

Steps to reproduce:

$ qemu-x86_64 -cpu Broadwell-v4 /usr/bin/detection
Program for detecting CCTags in one image, in a directory or in a video
For each image or video frame it detects the markers and it shows the image with a graphical overlayshowing the center of the tag, its ID and the outer ellipse:

Required input parameters:
-i [ --input ] arg Path to an image (JPG, PNG) or video (avi,
mov) or camera index for live capture (0,
1...) or to a directory containing the images
to process
-n [ --nbrings ] arg Number of rings of the CCTags to detect

Optional parameters:
-b [ --bank ] arg Path to a bank parameter file, e.g.
4Crowns/ids.txt
-p [ --params ] arg Path to configuration XML file
-o [ --output ] arg Output folder name
-s [ --save-detected-image ] Save an image with the graphical overlay of
the detected tags. For single images the saved
images will have a '_detected' suffix and it
will be placed either in the current directory
or in the directory given by --output. For
videos a file named #####.png will be saved
instead with the #s representing the
zero-padded frame number, either in the
current directory or in the directory given by
--output.
-u [ --show-unreliable ] Show the unreliable tags (marker id = -1)
