Public Class Form1
Private Sub Form1_Load() Handles MyBase.Load
Dim p As String = Application.StartupPath
PictureBox1.Image = Image.FromFile("image.jpg")
Dim ImageBgr As New Image(Of Bgr, Byte)(PictureBox1.Image)
Dim HaarXML As New HaarCascade("haarcascade_frontalface_alt_tree.xml")
Dim GrayImage As Image(Of Gray, Byte) = ImageBgr.Convert(Of Gray, Byte)()
Dim ImgGraphics As Graphics = Graphics.FromImage(PictureBox1.Image)
Dim MPen As New Pen(Brushes.YellowGreen, 8)
' Will take a several minute.. please wait..
For Each m In GrayImage.DetectHaarCascade(HaarXML)(0)
ImgGraphics.DrawRectangle(MPen, m.rect)
Next
End Sub
End Class
