#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 & Mac OS X
|
|
|
|
Install Go and OpenCV, you might want to install both of them via `apt-get` or `homebrew`.
|
|
|
|
```
|
|
go get github.com/lazywei/go-opencv
|
|
cd ${GoOpenCVRoot}/samples && go run hellocv.go
|
|
```
|
|
|
|
### Windows
|
|
|
|
- Install Go and MinGw
|
|
- install OpenCV-2.4.x to MinGW dir
|
|
- `libopencv*.dll` --> `${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
|
|
|
|
### Resizing
|
|
|
|
```go
|
|
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)
|
|
}
|
|
```
|
|
|
|
### Webcam
|
|
|
|
Yet another cool example is created by @saratovsource which demos how to use webcam:
|
|
|
|
```
|
|
cd samples
|
|
go run webcam.go
|
|
```
|
|
|
|
