MatchTemplate function causing exception

[absencelul]

After using MatchTemplate function I receive an Exception.

Description

func main() {
  haystack_img := gocv.IMRead("./test.png", gocv.IMReadUnchanged)
  needle_img := gocv.IMRead("./test2.png", gocv.IMReadUnchanged)
  result := gocv.NewMat()
  gocv.MatchTemplate(haystack_img, needle_img, &result, gocv.TmCcoeffNormed, gocv.NewMat())
  return
}

$ go run main.go

I've tried other things I saw which solved other peoples issues -

func main() {
  result := gocv.NewMat()
  window := gocv.NewWindow("hello")
  window.IMShow(result)
  return
}

This causes the same error as above...

I've also tried this which does not display an error. Obviously, I'm wanting to do a template match or comparison of an image within a image on 2 images and not just show the image in a window. I'm not sure exactly what I am doing incorrectly with MatchTemplate function above..?

func main() {
  img := gocv.IMRead("./test.png", gocv.IMReadUnchanged)
  window := gocv.NewWindow("test")
  window.IMShow(img)
  return
}

Steps to Reproduce

1. go run main.go

Your Environment

• Operating System and version: Windows 10 (Why does Microsoft make everything complicated?)
• OpenCV version used: 4.5.3
• How did you install OpenCV? using the win_build_opencv.cmd
• GoCV version used: 0.28.0
• Go version: go version go1.17.2 windows/amd64
• Did you run the env.sh or env.cmd script before trying to go run or go build? no

[absencelul]

This appears to be a window issue, I went ahead and followed the exact installation steps from my Linux machine, and the exact same code was executed and worked.

Would anybody be able to update the Windows 10 documentation on installing or suggest a build that is officially working?

[uglycow]

I get the same error with TemplateMatch on windows10, any solutions?

[uglycow]

@itiszac I fix it on windows by changing the IMRead options from "IMReadUnchanged" to "IMReadAnyColor", you may try it.

[lsymy]

I changed the IMRead options from "IMReadUnchanged" to "IMReadGrayScale" and then work. You saved my day! Thanks a lot!@uglycow

@itiszac : Operating System and version: Windows 10 (Why does Microsoft make everything complicated?) I can't agree more with you opinion.
