Re: [Mesa3d-users] Fastest way to grab pixel values in to memory (and file)

Hi

> How complex is the image recognition algorithm?
Well the function involves a matrix operations, calculating
expected values, covariances etc and obtaining the minimum
of the function values from the 100 frames.

Can GLSL calculate an arbitrary function like that?

Any good pointers for me to get started?

Many thanks

Srimal.
