Extract RGB values from images

[Tharuprabha]

Hi there,
Can someone help me to extract RGB values from images? I want to compare RGB values of two sets of pictures to identify a variety by it’s color.

Hello @Tharuprabha
This should be a simple task to be achieved in Python

Image Processing With the Python Pillow Library – Real Python

If you need further advice please provide details about the type compare analysis (visual, statistic…) . Besides some example of expected compare analysis outputs.

I’ve developed a couple of examples using Py Pillow image analysis (not RGB), already implemented in KNIME. You may want to check for insights:

Hello JKIers, As the other participants do, I’m enjoying this challenge as well; Do so, I’ve been kept working in and upgrading the solution. So aiming to keep you updated; I’ve added a functional requirement (Blurring Method), based in Python as well. This is the classical ‘Pixelation’. A combination of the two Methods (SVD + Pixelation) would be doable, but this is enough for the challenge. [image] Enjoy JKI-ing P.S. Pixelation % stands for amount of pixels.

P.S.- Maybe @mlauber71 already have some published examples for RGB analysis

Thank you!
I’m lack of coding knowledge. So this way is hard for me. But Thank you.
