Proposal for development in line edge method algorithm of FACE RECOGNITION

Line edge method is very well known method for face recognition. The target of this algorithm is generate a face like below

To obtain Line edge method follow below algorithom

  • First image convert to grayscale
  • Then image convert to binary by threshold value 127-128
  • Apply sobel edge detection
  • Calculate the edges value

so every step we get result like that

As a matter of fact we didn’t getting good line edge map by this, algorithm. If we use a improve algorithm instead of it like below we get a better result than first algorithom

  • First image convert to invert
  • Then image convert to grayscale
  • Apply sobel edge detection
  • Apply binary filter by threshold value  24
  • Apply thickening
  • Calculate the edges value

And the result come’s like

which extract more feature than previous algorithm.

    Respected sir,
    could you please possibly tell how to get the 3d coordinates of a human face.Suppose i have a foto with a front view with face.how can i extract the coordinate of the face.

    Thanks!!

    And sir i am surely new to emug cv. Could u Please give me a little code on how to get the rectangular coordinates from emug cv and visual studio.
