Installation
go get -u github.com/rocketlaunchr/showerglass/core
import "github.com/rocketlaunchr/showerglass/core"
Usage
import ("image/jpeg"; "os";)
import "github.com/rocketlaunchr/showerglass/core"
f, _ := os.Open("face.jpg")
defer f.Close()
opts := showerglass.Options{
NewHeight: 100.0,
NewWidth: 100.0,
ResizeAlg: showerglass.CatmullRom,
TriangleConfig: func(QRank, facearea int, Q float32, h, w int, c showerglass.MaxPoints) *showerglass.TriangleConfig {
if QRank < 1 {
// only modify first detected face
return &showerglass.TriangleConfig{
MaxPoints: 1500,
BlurRadius: 4,
BlurFactor: 1,
EdgeFactor: 6,
PointRate: 0.075,
}
}
return nil
},
}
masked, _, _ := showerglass.FaceMask(f, opts)
out, _ := os.Create("masked.jpg")
jpeg.Encode(out, masked, &jpeg.Options{Quality: 100})
Calibration
- A higher
MaxPointsmeans the face looks closer to the original. - A lower
MaxPoints(with the exception of0) means a more obfuscated face.
Based on the facearea, you need to calibrate MaxPoints to achieve the desired feel.
