Grouping the cells of a 1x2048 column according to brightness

Hi all,

I am trying to examine the cells of a 1x2048 column(derived from a video) and separate the column into several area that have similar brightness values. After calculating the mean value of each area, I should be able to map it to MIDI note.
It quite hard for me since I am quite new to Jitter.
Can anyone think of a way to do that?

Kind Regards,
Danny
