Hi all,
I was wondering if it would be possible to process images on a
low level using PIG. I want to be able to write a pig script
that can differentiate between two images.
Pig itself does not contain image processing primitives. But if you
write your image processing in a UDF, then Pig can be a great
framework for dealing with the parallelism, running it on Hadoop, etc.

Hi all,
To add in bit more details: You basically load images as bytearray
type. Pig wont interpret it. Then you can write a UDF which takes
these bytearrays as input. You can choose to work directly on
bytearray or create image objects out of them, do your processing and
return bytearray back to Pig. You
There was a slide desk sitting around google that had a 'facial recognition'
UDF a while back.

Hi,
We have a few projects which do this on hadoop, but I dont see any reason
why it cant have been done in pig.
