I want to do the following using my MV7:

1. take a picture(“image”)  
2.retrieve the pixel intensity data.  
3.view the pixel intensity data in a file that is readable by the OpenMV IDE editor.  
How do I do this?

Thanks  
Jim Sullivan

Hi, do Snapshot, then do get statistics, then open a file and write the object returned by get statistics to a file. The get\_stats object has a str() method so just need to write it to a file.

Do you need the exact code for this? I can easily give you a general outline but giving you the exact code requires me to find some time to do this which I don’t necessarily have (answering this on a train).

HI kwagyeman,  
I don’t want to look at statistics.

I want to look at each pixel’s data.

Thanks JLS

Hi, you can get each pixel value directly using get\_pixel(). However, it’s very slow to use in Python over a whole image. Get statistics returns the mean/median/mode/min/max/stddev and more for a region of interest which can be as small or large as you like.

Anyway, the choice of what to use is up to you.
