Good day. I'm working on a signature verification system and I've encountered a problem, can anyone help me? I am trying to add pixels to my current image so that when i warp the signature, it would would still be whole. This is my cropped image
Then when we warped it, it looks like this,
Some points are gone which would surely make verification less effective.
I wanna add pixels so it would like this,
(just edited with paint) This would then produce a warped image like the one shown below.
Also if you can suggest a better method to warp the signature for a more reliable verification would surely help. Thank you and I'm hoping you can help me.

The function padarray() in the Image Processing Toolbox does exactly that.
m = randi(255, 5, 5)
mPadded = padarray(m, [2, 2])
In the command window:
m =
97 19 174 94 224
203 152 113 203 183
192 160 23 2 129
167 35 111 65 16
33 6 181 84 31
mPadded =
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 97 19 174 94 224 0 0
