Error Correction Code for Images

Hello,

I wanted to ask about hamming code, in explanation he used (7,4) for redundant bits and total bits --7. Is that only an example or the standard size/formula? I have to do on 32x32 binary image. I am a bit confused here.

I need any other good method for ECC -- error correction code other than this hamming?

Thank you

have a great day!

That Hamming code is a special case of Hamming code. The total number of bits is 7, while the number of data bits is 4. It means that for error detection and correction purposes, there are 3 redundant bits, known as parity bits. The reason for its popularity as an example of a Hamming code is that it has one of the smallest sizes and possesses error correcting abilities.

The (7,4) Hamming code is an example, not a standard size
