Go bindings for OpenCV1.1

PkgDoc: http://godoc.org/github.com/chai2010/opencv

Install

Install GCC or MinGW (download here) at first, and then run these commands:

  1. go get -d github.com/chai2010/opencv
  2. go generate and go install
  3. go run hello.go

Notes

If use TDM-GCC, and build error like this:

c:\tdm-gcc-64\x86_64-w64-mingw32\include\aviriff.h:3:25: error: 'refer' does not
 name a type
 * No warranty is given; refer to the file DISCLAIMER within this package.
 ...

You need fix the C:\TDM-GCC-64\x86_64-w64-mingw32\include\aviriff.h header first:

** // fixit: ** -> /**
* This file is part of the mingw-w64 runtime package.
* No warranty is given; refer to the file DISCLAIMER within this package.
*/

	})
	win.CreateTrackbar("Thresh", 1, 100, func(pos int) {
		fmt.Printf("pos = %d\n", pos)
	})

	win.ShowImage(image)
	opencv.WaitKey(0)
}
