How to read individual image pixels?

[fromb2b]

Hi,

I would like to know wether it's possible to read image pixels individually instead of reading the entire image. The reason is that I need to store time series data for specific pixels and I don't have storage capacity for the entire image.

I am looking for a function that does individual reading in the form of:

nj.images.read("test.png")[x][y]

Do you have any suggestions?
