*an alg to know if a pixel is an outline pixel based on the pixels around it.

Code:
 Public Shared Function isOutLine(ByVal xPos As Integer, ByVal Ypos As Integer, ByVal image As Bitmap, ByVal bias As Integer) As Boolean

        Dim result As Boolean = False
        Dim change As Byte = 0
        If xPos > 0 And xPos < image.Width - 1 And Ypos > 0 And Ypos < image.Height - 1 Then
            Dim color1, color2, color3, color4, color5, color6, color7, color8, color9 As Color
            color1 = image.GetPixel(xPos - 1, Ypos - 1)
            color2 = image.GetPixel(xPos, Ypos - 1)
            color3 = image.GetPixel(xPos + 1, Ypos - 1)
            color7 = image.GetPixel(xPos - 1, Ypos + 1)
            color8 = image.GetPixel(xPos, Ypos + 1)
            color9 = image.GetPixel(xPos + 1, Ypos + 1)
            color4 = image.GetPixel(xPos - 1, Ypos)
            color6 = image.GetPixel(xPos + 1, Ypos)
            color5 = image.GetPixel(xPos, Ypos)

            If (CType(color5.R, Integer) > CType(color4.R, Integer) - bias) And (CType(color5.R, Integer) < CType(color4.R, Integer) + bias) Then
                change += 1

            End If
            If (CType(color5.G, Integer) > CType(color4.G, Integer) - bias) And (CType(color5.G, Integer) < CType(color4.G, Integer) + bias) Then
                change += 1

            End If
            If (CType(color5.B, Integer) > CType(color4.B, Integer) - bias) And (CType(color5.B, Integer) < CType(color4.B, Integer) + bias) Then
                change += 1

            End If
            If (CType(color5.R, Integer) > CType(color8.R, Integer) - bias) And (CType(color5.R, Integer) < CType(color8.R, Integer) + bias) Then
                change += 1

            End If
            If (CType(color5.G, Integer) > CType(color8.G, Integer) - bias) And (CType(color5.G, Integer) < CType(color8.G, Integer) + bias) Then
                change += 1

            End If
            If (CType(color5.B, Integer) > CType(color8.B, Integer) - bias) And (CType(color5.B, Integer) < CType(color8.B, Integer) + bias) Then
                change += 1

            End If
        End If

        End If
        Return result
    End Function
I'll delete the unused variables also.


this manages to detect outlines by checking per pixel and comparing to its surrounding, unfortunately it's very fucking expensive speed wize.
using parallal programming could speed it up by 4 but I should explore other directions
