Transform image in matlab

Hi ,Does anyone knows any functions to transform the left image to some kind of image like the right one?

The right one was created by using another software. I hope i can make a program on matlab to solve this problem

Thanks in advance.

If you can come up with a mathematical formula to move between rectangular coordinates and curved coordinates, then you can do the image warping using interp2()

The mathematical formula is the hardest part. I am newbie, so it is a little bit difficult for me. However i will try.

Thanks so much.
