Usage:< / h2 >
< p > This program uses OpenCV in order to recognize an image within an image. The return code is how many matches were found - return 0 for no matches, 1 for one match, etc.< / p >
< h2 > < a class = "anchor" id = "example" > < / a >
Example Usage:< / h2 >
< p > Match two images against the root X11 window:< / p >
< p > cva-match --x-root -s "< image_name> " -s "< image_name_2> "< / p >
< p > Match a root and sub image with a custom tolerance and search method< / p >
< p > cva-match -r "< root_image> " -s "< image_name> " -o 75 -m 1< / p >
< h2 > < a class = "anchor" id = "options" > < / a >
Full Options:< / h2 >
< p > -h, --help: Display this usage message.< / p >
< p > -u, --usage: Display this usage message.< / p >
< p > -r, --root-image: Location of the root image to compare against.< / p >
< p > -s, --sub-image: Location of the sub-image to find in root.< / p >
< p > -p, --separator: Separator of the X and Y coordinates.< / p >
< p > -t, --tolerance: Set how strict the match is - 100 is recommended lowest value.< / p >
< dl class = "note" > < dt > < b > Note:< / b > < / dt > < dd > When using CCORR or CCOEFF tolerance works in opposite direction, so -50 is recommended highest value.< / dd > < / dl >
< p > -m, --search-method: Set which method is used to search for sub-images.< / p >
< dl class = "note" > < dt > < b > Note:< / b > < / dt > < dd > Search Methods: CV_TM_SQDIFF = 0, CV_TM_SQDIFF_NORMED = 1, CV_TM_CCORR = 2, CV_TM_CCORR_NORMED = 3, CV_TM_CCOEFF = 4, CV_TM_COEFF_NORMED = 5< / dd > < / dl >
< p > -x, --x-root[=DISPLAY]: Set the root image to come from X11< / p >
< dl class = "note" > < dt > < b > Note:< / b > < / dt > < dd > The DISPLAY variable is optional, not specifying it will cause X to use the default display (not specifically :0.0)< / dd > < / dl >
< p > -c, --center: The output points should be centered on the sub-image, rather than the top-left corner.< / p >
< p > -o, --sane-tolerance: Set the tolerance using a scale of 1-100, rather than INT_MIN to INT_MAX (100 ~= INT_MAX)< / p >
