Yes, it is possible, since the API will return the rectangle coordinates of the detected faces. You only need to subtract the subregions of the detected faces from the original image.
A use case scenario should look like the following:
type SubImager interface {
SubImage(r image.Rectangle) image.Image
}
//.....
// Run the classifier over the obtained leaf nodes and return the detection results.
// The result contains quadruplets representing the row, column, scale and detection score.
dets := classifier.RunCascade(cParams, 0.0)
// Calculate the intersection over union (IoU) of two clusters.
dets = classifier.ClusterDetections(dets, 0)
for i := 0; i < len(dets); i++ {
if dets[i].Q >= 5.0 {
rect := image.Rect(
dets[i].Col-dets[i].Scale/2,
dets[i].Row-dets[i].Scale/2,
dets[i].Scale,
dets[i].Scale,
)
subImg := img.(SubImager).SubImage(rect)
bounds := subImg.Bounds()
// Do whatever you want with the subImg
}
}
I will try this. Thank You
Hi, Thanks for the great work here.
Is it possible to use pigo to extract faces from a photo and save the extracted faces individually.
