What OCR4Screen is
OCR4Screen let’s other computer programs "see" all the graphical objects on the
display screen in a fraction of a second. No other technology in the world comes
close to the speed and accuracy of OCR4Screen.
OCR4Screen can recognize thousands of different graphical objects from millions
of possibilities, typically processing the entire display screen in less
than 1/10 second.
How OCR4Screen Works
OCR4Screen is similar to OCR (Optical Character Recognition) technology except
that it is 100% accurate and at least 100-fold faster. OCR4Screen can recognize
every kind of graphical object, including character glyphs and graphical user
interface controls.
The reason that OCR4Screen is so much faster and accurate than OCR technology is that
OCR4Screen only processes exact matches of pixel patterns. Technically this is called
a deterministic process as contrasted with the stochastic process that OCR uses.
This difference has the advantage that it can be much faster and 100% accurate.
The disadvantage is that OCR4Screen can only process machine generated character glyphs
(and other graphical objects) that always have exactly the same set of pixels.
This prevents OCR4Screen from converting printed documents to editable text,
like OCR. Unlike OCR, it allows OCR4Screen to recognize tiny character glyphs at display
screen resolutions with 100% accuracy. OCR loses accuracy at (96 DPI) display screen
resolutions.
OCR4Screen is able to search for millions of different graphical objects
simultaneously, rather than making comparisons one at a time because it
is based on a Deterministic Finite Automaton (DFA) which is inherently
capable of matching many different patterns at-a-time.
OCR4Screen processes each of these graphical objects as 24-bit bitmaps.
OCR4Screen was designed so that it can simultaneously process rectangular
bitmaps of different sizes and shapes and colors.
Since OCR4Screen processes text as rectangular bitmaps including the
background color, OCR4Screen can process text and other non-text graphical
objects in a single pass over the screen pixel data.
