Can anyone help me with image warping?

Good day. I'm currently doing a signature verification system that requires a photo to be warped, this my current warped image.

When i saw the result of my warping, a thought formed in my mind that this may not be the best warping method for our project since it would make verifications less reliable. I am hoping that someone can help me come up with a better way of warping images for a more successful verification. Thank you

Do you realize that we have no idea why you would want to warp the signature in the first place as part of a verification system and therefore cannot suggest improvements?

The only warping I can think of that might be useful in signature verification would be to straighten out baselines and make the signature more linear and horizontally aligned.

warping is the method we were assigned to do to perform our verification. its like the images should align after warping if they are both from the same person

I think you're right, sort of. But I don't think it's the warping method per se that is the problem, but rather the parameters you're passing to it. I certainly don't think you're helping your task of identifying the signature, or doing OCR on it, by swirling the signature like that. Why are you doing that? Certainly it must be better before you did that, than after.

i am doing signature signature verification and the method assigned to us is warping. we were given a method of warping though we can'd do it. shown below is our supposed method.

since we can't do it we decided to have our own warping method and swirling is what we ended up with. after warping our signatures, we are supposed to overlap them then we would do AND-ing of those. once done with anding. we would count the pixels left after and compare it to the number of pixels of our genuine signature

So, since you couldn't replicate the "word morphing correspondence algorithm" that paper successfully used you decided to just swirl the signatures and thought that would work. That's pretty funny.

yes, we don't know how we can do what they did that is why we just swirled it. we looked for other methods for warping but swirling is the only one we can do.
