Now I want to transform an image to another coordinate. For original image, the pixel is defined as (u, v), and transformed image's pixel (u',v') can be calculated using the following equation. u'=f(L1*u+L3*f)/(-L3*u+L1*f); v'=f*v/(-L3*u+L1*f); L1,L3,f are the parameters which values is known.

After the transform, the image (left) should become like right image. I have no idea how to do this? Should I calculate the pixel values u' and v' and use the interp2? I tried but didn't work out. Please give me some advices. Thank you.

Yes, I'm using Windows 10. Your code above doesn't do anything with images. It just defines some anonymous functions.

Sorry I forgot the rest part, the rest part is the same with the code from your link. Thank you for answering my question. I am using IOS, maybe it is the reason why error occurs. I will find a windows system computer to try it.
