Image recognition in .NET ?

[gicio]

Hi!

 

I am looking for something like image recognition in .NET.

 

Short story what will I do:

 

Imagine I have a jpeg picture with a man on it. The background is

much brighter as the man on it. Imagine it so:

You have a white paper and a black figure on it.

 

I will automatically add 10 textboxes on the picture. But the 10 textboxes

can not be positioned on any part of the figure.

I need a framework or a sample code to recognize the image and set automatically

the 10 textboxes of any position on the picture where the background is

white.

 

do you know any sample code or a open source framework that provide

me this possibility?

 

Regards,

I think you need to loop through and examine the picture's pixels for color intensity

 

       Dim bmp As New Bitmap(myPortrait.bmp)
       Dim x, y As Integer
       For y = 0 To bmp.Height - 1
           For x = 0 To bmp.Width - 1
               If Not bmp.GetPixel(x, y).ToArgb = 0 Then  '0 being a transparent pixel
                   If bmp.GetPixel(x, y).B > 10 Then
                      'this finds the black color intensity and might be what will work
                      'x and y are the pixel coordinates within the bmp picture
                   End If
               End If
           Next
       Next

You could always use: the Open Computer Vision Library (OpenCV) which was formally an intel project but is now open source.

 

It isn't .net but it is pretty nice from what I hear from the robotics society :)
