Just a quick comparison of Vis2 and Capture2Text on text from the Vis2 github page:
Original text on Vis2 github page (large font):
Vis2 - OCR()
(Capture2Text)
Q’JViSZ - OCRO
(Vis2)
Vis2 - OCROQ

Very accurate

in the git you write

"Press Alt + Space to get the coordinates of the grey rectangle."

When I do this on windows 10 some little text popups up on upper right of screen that says x y h w but it has no data

can you tell me the steps to make it work ?

@ferryiol I changed

Code: [Select all] [Download] GeSHi © Codebox Plus

               Vis2.Graphics.Subtitle.Draw("x: " this.x1() " │ y: " this.y1() " │ w: " this.width() " │ h: " this.height()
to

Code: [Select all] [Download] GeSHi © Codebox Plus

Vis2.Graphics.Subtitle.Draw("x: " x " │ y: " y " │ w: " w " │ h: " h
on Github, does latest version fix it?

UPDATE: Added ImageIdentify() - use it to identify objects in images. Is it useful? probably not. But it is fun to use.

USER WARNING Abuse of ImageIdentify() will get you temporarily IP banned by Google. (<12 hours) If you would like to continue using it after the ban, please sign up for a free google account and get a Cloud Vision API key and input it into the popup. Free 1000 images per month I think.

Re: Vis2 - OCR(), ImageIdentify()

Hi,

I am also having troubles on Windows 10 Home 64-bit.

I have downloaded the latest version from https://github.com/iseahound/Vis2/archive/master.zip

It works in interactive mode, but when I try to use the other methods I get the blank box problem.

Code: [Select all] [Download] GeSHi © Codebox Plus

#include <Vis2>  ; Equivalent to #include .\lib\Vis2.ahk


MsgBox % OCR("test.jpg") ; << Does not work

#c:: OCR() ; << Works perfect!
Esc:: ExitApp


I also tried the WinTitle (using notepad) and URL methods, which also did not work.

I ran the DetectBugs script posted earlier in this thread and I get this error:

https://i.imgur.com/0TZQk5P.png

From here, I did some further digging and this is what I found:

Code: [Select all] [Download] GeSHi © Codebox Plus

; Line 2140 of Vis2.ahk
_cmd .= q this.tesseract q " --tessdata-dir " q fast q " " q in q " " q SubStr(out, 1, -4) q


%out% contains only the filename without extension, so the SubStr does not remove the extension (as I think intended?) and instead shortens the actual name.


    Vis2_screenshot2f379028-4dde-47c6-b9f6-9b3713be8123.bmp
    Vis2_preprocess2f379028-4dde-47c6-b9f6-9b3713be8123.tif
    Vis2_text2f379028-4dde-47c6-b9f6-9b3713be.txt

Is an example of what gets created on my system.

Then %out% is looking for the full file name and this of course does not exist so the exception is thrown.

If I remove the SubStr and append the .txt to %out% then I can get DetectBugs to run.

Code: [Select all] [Download] GeSHi © Codebox Plus

_cmd .= q this.tesseract q " --tessdata-dir " q fast q " " q in q " " q out q
;_cmd .= q this.tesseract q " --tessdata-dir " q fast q " " q in q " " q SubStr(out, 1, -4) q

; (...snip...)

out := out . ".txt


And my results are:

    No text file found. #1
    Test2: No text file found. #2

Regards. :)

[edit] Also, when I run my main script again:

Code: [Select all] [Download] GeSHi © Codebox Plus

#include <Vis2>  ; Equivalent to #include .\lib\Vis2.ahk


MsgBox % OCR("test.jpg") ; << Does not work

#c:: OCR() ; << Works perfect!
Esc:: ExitApp


The file that gets created in my temp has two extensions:

Vis2_text38ed24b5-3fc9-4feb-8a57-b4057148aee2.txt.txt

I'm getting the blank box again on Win7, 64-bit also. Version from 3-31-18 still working fine :D
About a missing extension, though - the intermediate file has no extension, it gets processed to text later. That's why your mod is giving you a file with .txt.txt.
Here's what it looks like on my system (in the %temp% folder, after running the 3-31-18 working version):

@bhanson @burque505 It should be fixed now. https://github.com/iseahound/Vis2

EDIT: Also ImageIdentify() will work with input files now. Like ImageIdentify("test.jpg")

I'm getting an error trying to call OCR() on the same bitmap with different coordinate options.

Running OCR() on a bitmap using the 3rd parameter as coordinates seems to destroy the original bitmap.

Code: [Select all] [Expand] [Download] GeSHi © Codebox Plus



Is this intended?

[edit] I know of course I can clone the portion of the image I want to process before sending to OCR(), but I guess I expected OCR to not modify the source input.

No that is an oversight of mine. It is fixed on GitHub.

Some ImageIdentify() examples:

Code: [Select all] [Download] GeSHi © Codebox Plus

MsgBox % ImageIdentify("https://i.imgur.com/ffnoUVR.jpg")

modern art (90%), art (87%), painting (69%), visual arts (61%), paint (61%), acrylic paint (61%), artwork (60%), graphics (57%), graphic design (51%)

Code: [Select all] [Download] GeSHi © Codebox Plus

MsgBox % ImageIdentify("https://i.imgur.com/ffnoUVR.jpg",,[113,159,151,91])

orange (92%), fish (92%), product (74%), fish (60%), animal figure (56%)

Fun to play around with. There's a lot of potential. General Question: How are you using Vis2? For me it's basically a toy project. I prefer the GUI, since it allows me to extract text from websites that disallow text selection.

Hi, iseahound, this code caused AHK_L 64-bit, 1.1.28.01, to crash, and my Win7 SP1 64-bit computer to lock up completely:

Code: [Select all] [Download] GeSHi © Codebox Plus

MsgBox % ImageIdentify("https://i.imgur.com/ffnoUVR.jpg")

Tried it three times, same result, not really ready to do it again :)

I think it works now. I commented out ObjRelease(pStream) in 3 areas, but I don't know why it's causing crashes. Does RtlMoveMemory delete the source data?

iSeaHound: I just tested the script on Win 10 x64 and it works well.

I am having eye-sight issues and I am very interested in such a tool, but I would like the process simplified / automated... I want to have it capture the text underneath the mouse cursor by detecting the line of text underneath, looking at close letters or something. Is it possible?

Best regards, Marius.

I suspect that is possible because he allows you to do an ocr based on x y w h, so you can detect the xy of the mouse and then do an ocr

Yes, it would be only a matter of identifying the boundaries of the text line[s] underneath the mouse cursor...

Hello, again!

@ iseahound: would this be useful? http://www.danvk.org/2015/01/07/finding ... numpy.html

I found this bit of information trying to understand how this would be done [detect the boundaries of text].
