Hi gemers, hi list,
I am looking for an object or a combination thereof that can give me the mean pixel value of a specific region of an image.
Is there a way to do this in Gem ?
I would like to implement color tracking in different regions of an image.

use [pix_crop] for getting the specific region (rectangles only) use [pix_mean_color] (CVS) for getting the average color of an image. OR use [pix_resize 1 1] (CVS) to resize the image to 1 pixel and get the value of that image with [pix_data] or [pix_dump]
OR convert the image to a signal and use [lop~]

Thanks, works great. One question: why is the output of pix_mean_color scaled to 0-255 whereas the rest of Gem colors are between 0-1 ?

mm, don't want to insist but pdp_cropper -> pdp_hue does this, and i perfectly know it's not gem...

yes, well, bom dia. thats for the next time. I wanted to do computer vision with pdp, but you know that I couldn't quite finish the port to the evil system .. so its Gem for now.
And next year gridflow, to be fair.

pix_data for each pixel and then comparing the results.... ...hope your resolution is not too high ;)
