calculating entropy of an image

in General Discussion • Other • 7 months ago

Hi list, i was wondering if anybody have implemented shannon's entropy in processing?

i was wondering how can i use shannon entropy for measure the entropy of a image? or group of pixels?

do anybody have tried implementing this? or any idea how to implement this?

cheers

I would search the Internet, first to know what it is about (no idea, at the time of writing), second, to find out if there is a usable Java implementation somewhere.

Hi, ive found this implementation in java.

http://whaticode.com/2010/05/24/a-java-implementation-for-shannon-entropy/

This implementation calculates the entropy of a string, but i was wondering how can i use the same to calculate the entropy of an image?

I was thinking iterating in all the pixels of an image an then get its pixels value and then convert all those pixels values into string.

do you think this should work?
