It doesn't work on image with even size.

Hey thanks for the code,
but the error that persists is that in the noisy data again the fitting is coming out to be wrong. It fits the co-ordinates the data for noisy data as well.

I am implementing the code on a Image processing method.

Maybe someone has matlab code to eliminate camera distortion? This code doesn't do that :(

it's really cool，man，just replace the function isrgb when you are using a new matlab version（R 8.0+）

Nice! This works well for my cell tracking application.

If you want to learn more about the method, take a look at the lecture that this code is based on:

Nice work!

Any idea how to get a fully cropped image? Without the black surroundings? Would be really helpful. Thank you

Hi,

If anyone has the m code (or in any other other form) implementation of siftWin32.exe (the SIFT algo), pls upload or email me at pallavi.ganotra@tcs.com.

Thanks a lot!

Hi Edward,
could you tell me what literature you used for this algorithm?
Was it by any chance:
1. Pyramidal Implementation of the Lucas Kanade Feature Tracker
Description of the algorithm?

Hi Edward,

How do you use your algorithm?
Is there any demo?

I'm able to see what to do with X2 and Y2?
