How to trace objects with gocv?

1. install OpenCV for gocv. [how to install]

2. run gocv code [github]
  • run command : 
    • $ go run gocv_example02.go 0 ../../data/lbpcascades/lbpcascade_frontalface.xml  

3. show camera

[OpenCV] What is gocv?

Image
GoCV           The GoCV package provides Go language bindings for the  OpenCV 4  computer vision library. The GoCV package supports the latest releases of Go and OpenCV (v4.0.0) on Linux, macOS, and Windows. We intend to make the Go language a "first-class" client compatible with the latest developments in the OpenCV ecosystem. GoCV also supports  Intel OpenVINO . Check out the  OpenVINO README  for more info on how to use GoCV with the Intel OpenVINO toolkit. How to use Hello, video This example opens a video capture device using device "0", reads frames, and shows the video in a GUI window: package main import ( " gocv.io/x/gocv " ) func main () { webcam , _ := gocv. OpenVideoCapture ( 0 ) window := gocv. NewWindow ( " Hello " ) img := gocv. NewMat () for { webcam. Read (&img) window. IMShow (img) window. WaitKey ( 1 ) } } Face detect This is a more complete example that opens a v...
