Attempt to execute SCRIPT matchGMS as a function: #432

Closed krishnakumarrs closed 5 years ago

krishnakumarrs commented 5 years ago

I tried to execute gms_matcher file from samples but i am receiving this error message.

please help. thanks

amroamroamro commented 5 years ago

It probably means you haven't compiled the MEX-files?

Please follow the build instructions in the README file and wiki.

PS: The gms_matcher_*_demo.m sample uses cv.matchGMS from opencv_contrib modules, so you must build mexopencv against both opencv and opencv_contrib. (basically anything under the opencv_contrib/ directory requires the contributed modules)

krishnakumarrs commented 5 years ago

I have compiled the mexopencv from mexopencv_master folder. And also surf descriptor is working. but gms is not. I am using mac. please help.

amroamroamro commented 5 years ago

What opencv version did you build against? Are you using opencv_contrib? Also how did you build/install opencv?

Post the output of this:

General configuration for OpenCV 3.4.3 ===================================== Version control: unknown

Extra modules: Location (extra): /Users///opencv_contrib-3.4.3/modules

amroamroamro commented 5 years ago

Can you show the full output? for starters I'm interested to see the list of modules built.

Normally for mexopencv functions, you would have a .m doc-file and a corresponding .maci64 mex-file. The error message "attempt to execute SCRIPT as a function" simply means the mex-file is missing and was not compiled.

So if you describe how you compiled opencv and mexopencv, I could help figure out the problem. You're not giving us much info here...

Please note that the current version of mexopencv targets opencv 3.4.1, your comment indicates you're using 3.4.3 instead. I suspect that may be the cause, you should use the supported version.

i have used homebrew to install opencv

amroamroamro commented 5 years ago

You didn't mention, but did you get any compile errors when building mexopencv?

Bottom line is you have to use the currently supported version of opencv 3.4.1 (I'm working on updating mexopencv to target opencv 3.4.2, 3.4.3, 3.4.4 soon)

I'm not a mac person, but I think you can do something like this to install a specific version of a homebrew formula:

$ brew install opencv@3.4.1
# with any other options like: --with-contrib

Otherwise you could also compile opencv/opencv_contrib from source yourself. See the wiki (instructions are for linux, but should be similar).

krishnakumarrs commented 5 years ago

I have compiled with opencv3.4.1 still i get the same error. please help.

amroamroamro commented 5 years ago

Please describe in detail the commands you use to build both opencv/opencv_contrib and mexopencv. I think you're missing something, but I can't help without you providing more info..

amroamroamro commented 5 years ago

Ok just to be sure, when you compile mexopencv, you are calling:

$ make all contrib

not just:

$ make

right?

krishnakumarrs commented 5 years ago

opencv 3.4.1 and opencv_contrib 3.4.1 --- make MATLABDIR=/Applications/MATLAB_R201a.app PKG_CONFIG_MATLAB=opencv3 LDFLAGS=-L/Users⁩/----/-------/⁨opencv-3.4.1⁩/⁨build⁩/lib -j2

amroamroamro commented 5 years ago

That explains it then, make alone doesn't compile opencv_contrib modules for mexopencv, you have to build both all and contrib targets.

So the call should be:

 $ make MATLABDIR=.. PKG_CONFIG_MATLAB=opencv3 -j2 all contrib

Since you already have compiled without contrib, you'll have to do make clean first to avoid linking errors regarding MxArray.

krishnakumarrs commented 5 years ago

Thanks it worked.
