You can refer #40
He noted sample source code to load from OpenCVSharp.
from facerecognitiondotnet.
Sorry takuya-takeuchi, I'm still not getting the reference.
I got a cropped grayscale Mat from opencvsharp as I use haarcascade to do a rough detect.
I also tried
var array = new byte[source.Height * source.Width];
source.GetArray(source.Width, source.Height, array);
var image = FaceRecognition.LoadImage(array, source.Height, source.Width, 1);
from facerecognitiondotnet.
Last argument of LoadImage is not 1. It is stride. stride is width * channels.
So it is width * 1 if grayscale.
from facerecognitiondotnet.
Oh, sorry. You are correct. Last argument is element size.
from facerecognitiondotnet.
But still I got ArrayOutOfRangException. So I tried
var array = new byte[source.Height * source.Width];
source.GetArray(source.Rows-1, source.Cols-1, array);
var image = FaceRecognition.LoadImage(array, source.Height, source.Width, 1);
var encodings = faceRecognition.FaceEncodings(image).ToArray();
But the encodings.Length is 0.

Could you check the following sample? I wrote sample project using OpenCVSharp.
It may be helpful.

Thank you so much. It worked!
