#Go OpenCV binding

Why fork?

Original project (https://code.google.com/p/go-opencv) looks abandoned. Therefore, I decide to fork it and host it on Github, so that others can help to maintain this package.

Install

Linux

• install Go1 and OpenCV
• go get github.com/lazywei/go-opencv
• cd ${GoOpenCVRoot}/samples && go run hellocv.go

Windows

• install Go1 and MinGW
• install OpenCV-2.4.x to MinGW dir
  • libopencv*.dll --> ${MinGWRoot}\bin
  • libopencv*.lib --> ${MinGWRoot}\lib
  • include\opencv --> ${MinGWRoot}\include\opencv
  • include\opencv2 --> ${MinGWRoot}\include\opencv2
• go get code.google.com/p/go-opencv/trunk/opencv
• cd ${GoOpenCVRoot}/trunk/samples && go run hellocv.go

Example

package main

import opencv "github.com/lazywei/go-opencv/opencv"

func main() {
	filename := "bert.jpg"
	srcImg := opencv.LoadImage(filename)
	if srcImg == nil {
		panic("Loading Image failed")
	}
	defer srcImg.Release()
	resized1 := opencv.Resize(srcImg, 400, 0, 0)
	resized2 := opencv.Resize(srcImg, 300, 500, 0)
	resized3 := opencv.Resize(srcImg, 300, 500, 2)
	opencv.SaveImage("resized1.jpg", resized1, 0)
	opencv.SaveImage("resized2.jpg", resized2, 0)
	opencv.SaveImage("resized3.jpg", resized3, 0)
}
