[(S tier) puzzle] the development of an A.Eye for AGI GFs

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

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

main :

Imports System.Math
Public Class Form1
    Dim eye1 As New Aeye()
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim bmp As New Bitmap("c:\testimage\x1.bmp")
        Dim bmp2 As Bitmap = bmp.Clone()
        PictureBox1.Image = bmp.Clone()

        For i = 1 To bmp.Height - 2
            For j = 1 To bmp.Width - 2
                If Not Aeye.isOutLine(j, i, bmp, 20) Then
                    bmp2 = Aeye.mark_dark_pixel(j, i, bmp2, 1)
                End If






            Next
        Next

        PictureBox2.Image = bmp2.Clone()
