Send an image to yolo (darknet) and receive object position and type

Question

Is there a possibility to send an image from C# to yolo and receive all detected object positions and types.

For example on the demo image

type      | x   | y   | width | height
-------------------------------------------
bicycle   | 214 | 150 | 450   | 378
dog       | 150 | 260 | 210   | 350
truck     | 540 | 100 | 250   | 150

Example code

public class Yolo
{
    public ObjectPosition[] GetObjects(Image image)
    {
        //return yolo result
    }
}

public class ObjectPosition
{
    public string Type { get; set; }
    public int X { get; set; }
    public int Y { get; set; }
    public int Width { get; set; }
    public int Height { get; set; }
}

PM> install-package Alturos.YoloV2TinyVocData

Code example

using (var yoloWrapper = new YoloWrapper("yolov2-tiny-voc.cfg", "yolov2-tiny-voc.weights", "voc.names"))
{
    var items = yoloWrapper.Detect("image.jpg");
}
