Face recognition bindings about gocv HOT 12 CLOSED

@andboson Hi, do you have any code samples on how to do basic face recognition ?

from gocv.

Hello @andboson we do not yet have bindings for that module.

It is part of opencv_contrib which is compiled into OpenCV if you follow our instructions, so it should be a matter of adding bindings in the same fashion that we have for other modules.

We would be very glad to accept a PR that added this functionality!

from gocv.

OK @andboson I'm working on some code to show how to pass a []Mat as the needed param. More soon!

from gocv.

OK, here is how example of how to handle []Mat

The Merge() function takes a slice of Mat as param:
https://github.com/hybridgroup/gocv/blob/dev/core.go#L309

Here is the associated C impl:
https://github.com/hybridgroup/gocv/blob/dev/core.cpp#L148

That should get you going. Please let me know if that is enough, or if there is anything else I can do to help.

This is one very easy way to handle http://blog.campoy.cat/2014/03/github-and-go-forking-pull-requests-and.html

In the latest work in the dev branch, I have just added a contrib sub-package. This is where an implementation of the OpenCV contrib face module would go...

Hello
I tried to work with C in Go (first time).
Main question is how to pass function parameters from Go to C.
How I can convert slice of Ints to C vector of C.int and slice of Mat to C vector of C.Mat?

from gocv.

Hello @andboson what specifically are you trying to do? Mat typically wraps around all values. Check out here for tests that also show how to reference them:

from gocv.

I need pass slice of Mat`s to Facerecognizer->train(vector, vector,bool)

from gocv.

Thank you!
I`ve got the first recognition! ) (used original gocv code)
But how I can run tests (and work) on fork?
I got error on my fork:

drew@drew-Aspire-E1-571G ~/Gopath/src/github.com/andboson/gocv (master) $ go test ./...

from gocv.

Big thanks!
Maybe close this issue tread?

ps: but exists errors in my PR...

from gocv.

Thanks for the PR @andboson now closing this issue.
