    I'm not sure what you mean by text extraction. Are you referring to stenography or fuzzy interpretation of text inside a raster image? The latter is pretty advanced stuff.

    It's possible but in the same order of complexity as facial recognition. You or I can look at an image and read the text. A computer has to be instructed on how to interpret the raw data. It will involve pattern recognition heuristics and self correcting feedback like a genetic algorithm to incrementally make better predictions.

    Seriously complex stuff.
