Ashley you havent understood what i wrote or i have formed my though not clearly.

my idea is to not detect a singel pixel but a grid box , and each bos is made by many pixels

for example: a window with resolution of 100 x 100 pixels would have 16 grid box (25/25 pix each)
like with tiles where you can set the tile width and heigh.

I'm not sure I understand. How does that improve performance?

Grid box or not, you're transferring pixels. Just the act of looking up one pixel creates the slowdown.

I don't think you can get anything other than a single pixel. Even if you could detect a quadrant, what if there's more than one color within that group?
You would need some sort of algorithm to get a mean, and that would undoubtedly slow it down even more.
