Windows 10 OCR and Face detection

fryquez · Post by **fryquez** » Tue Aug 31, 2021 11:54 am

Thanks to our friends on the autohotkey forum, we now have access
to Windows 10 Optical Character Recognition and Face Detection.

The Windows Runtime needs MULTITHREADED thread initialization.
But your main (GUI) thread needs SINGLETHREADED initialization.

So this example uses a temporary thread.
If you want to use it in your program, you should use a worker thread instead.

I don't know if I will ever use it but it works great, really impressive

Thanks fryquez for sharing this beautiful code

Big thx fryquez!! This is really great! Thank you very much! This opens up many new possibilities

Only one word !!!

SPLENDID !!!
Never i believe W10 can do that natively

That can be really usefull

Thanks a lot for sharing this jewel

Great Job!!!!!!

Unfortunately, the face recognition does not recognize that much at the moment. Is there a way to improve the quality of the search?

fryquez · Post by **fryquez** » Wed Sep 01, 2021 5:02 pm

No, I guess not. The used Interface, does not seem to have any options.

BarryG · Post by **BarryG** » Thu Sep 02, 2021 12:38 am

Thanks, but there's a bug in this somewhere, because I chose an image with 4 faces (and no text) but it shows text from the source code in the IDE:

Brilliant.

Who would do to specify the rectangle of the part of the screen where the text is located?

infratec · Post by **infratec** » Thu Sep 16, 2021 9:04 am

First easy (and ugly) way to select an area:

Code: Select all

OpenWindow(0, 0, 0, 400, 200, "Select your area", #PB_Window_SystemMenu|#PB_Window_SizeGadget|#PB_Window_ScreenCentered|#PB_Window_Tool)
SetWindowColor(0, #Blue)
SetWindowLong_(WindowID(0), #GWL_EXSTYLE, #WS_EX_LAYERED|#WS_EX_TOPMOST)
SetLayeredWindowAttributes_(WindowID(0), #Blue, 0, #LWA_COLORKEY)

Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

Debug "x: " + Str(WindowX(0, #PB_Window_InnerCoordinate))
Debug "y: " + Str(WindowY(0, #PB_Window_InnerCoordinate))
Debug "w: " + Str(WindowWidth(0))
Debug "h: " + Str(WindowHeight(0))

;tOCR_DEMO\ImageID = HBitmapFromScreen(x, y, w, h)

infratec · Post by **infratec** » Thu Sep 16, 2021 9:38 am

Second version, maybe nt better, but different:

Code: Select all

#Win1 = 1

OpenWindow(#Win1, 0, 0, 400, 200, "", #PB_Window_ScreenCentered|#WS_SIZEBOX|#PB_Window_BorderLess|#WS_BORDER)
SetWindowColor(#Win1, #Blue)
SetWindowLong_(WindowID(#Win1), #GWL_EXSTYLE, #WS_EX_LAYERED|#WS_EX_TOPMOST)
SetLayeredWindowAttributes_(WindowID(#Win1), #Blue, 0, #LWA_COLORKEY)

Repeat
  Event = WaitWindowEvent()
  Select Event
    Case #PB_Event_LeftClick
      Exit = #True
    Case #PB_Event_RightClick
  EndSelect
  
Until Exit

Debug "x: " + Str(WindowX(#Win1, #PB_Window_InnerCoordinate))
Debug "y: " + Str(WindowY(#Win1, #PB_Window_InnerCoordinate))
Debug "w: " + Str(WindowWidth(#Win1))
Debug "h: " + Str(WindowHeight(#Win1))

;tOCR_DEMO\ImageID = HBitmapFromScreen(x, y, w, h)

Hello,

Frankly nice, it will surely be practical for me. Thank you
