What is moments of image?

Hello everyone!

I have to implement the Zernike moments for feature extraction in Signature Recognition System, If someone know, give me a brief description about image moments and Zernike moments and also I have gotten the source code of Zernike moments from mathwork site from this link: http://www.mathworks.com/matlabcentral/fileexchange/38900-zernike-moments

It gives me tow value from image and I don't know what are the tow value, if someone know explain me that, please answer me I need it very hard.

thank you.

Your question is very broad to be answered fully here. There are many tutorials on Zernike moments that you can find online with a simple search.

At a high-level - Zernike moments are essentially descriptors for quantifying shape of an object (typically in a binary image). They are rotational invariant, are can be adapted to be translation (shift) and scale invariant.

I don't see a 'tow' value anywhere in this submission. Where do you see it?

thank you sir!

I have given a link on my above question, I got the code of Zernike moments from that link and I run this code, this code return tow value.

please response me.

thanks

We can't until you define what tow is. Do you mean two (2) instead? Tow means to pull something, like a car.

whether Zernike Moments can use for the image that contain the four image like this ?
