Hello I wondering how to read more complicated text from image with Tesseract or other method.
I used this script and it works with simple text on white background
I need to read text which looks like this
What I need to do?
Download fonts or something from there https://github.com/tesseract-ocr/tesseract
gimme some info please
$OCR_Result = _TesseractScreenCapture(0,"",1,2,220,660,500,730,1)
$OCR_Result1 = _TesseractScreenCapture(0,"",1,2,220,660,500,730,1)
$OCR_Result2 = _TesseractScreenCapture(0,"",1,2,220,660,500,730,1)
$OCR_Result3 = _TesseractScreenCapture(0,"",1,2,220,660,500,730,1)
$sound = _SoundStatus("C:\ExpertAdvisorBuyAlert.wav")
while _nowtime < 3.30 pm
If $sound = True Then
if $OCR_Result1 > $OCR_Result2
Trying to ocr some values on chart in real time(once per minute) and buy/sell securities on basis of alert generated in my software.
I am struck onto few steps.
1. On Tesseract Screen Capture indentation parameters. How can we determine the exact parameters if I just want numeric values only.
2. The Tesseract Screen Capture generates and error Obj1 on line 185 which needs to be resolved.
3. Sometimes lines get overlapped with values. What to do in that case.
3. Detecting the sound as and when it approaches and then comparing the ocr values to decide on either buy or sell.
The values that needs to be fetched are encircled.
i have this picture here *attached* and this script here:
$ImageToReadPath = @MyDocumentsDir & "\GDIPlus_Image2.jpg" $ResultTextPath = @MyDocumentsDir & "\Result" $OutPutPath = $ResultTextPath & ".txt" $TesseractExePath = @MyDocumentsDir & "\Tesseract.exe" ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE) If @error Then Exit MsgBox(0, "Error", @error) EndIf MsgBox(0, "Result", FileRead($OutPutPath)) FileDelete($OutPutPath)
but tesseract doesnt recognized the correct word... and gives me trash back...
this is the image >>
and the result was >> "samm"
the image was an normal jpg and generated with this code here:
_ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image2.jpg", 712,268,853,284)
Could anybody give me a hint what i can do better to get this easy image to text?
thank u very much!!!
Edit: i also tried to capture the screen as bmp with a higher resolution... nothing changed...
_ScreenCapture_SetBMPFormat(4) _ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image.bmp", 712,279,853,295)
I'm trying to get Tesseract to work using the example script here: https://www.autoitscript.com/forum/topic/174483-tesseract-simple-example/ Downloading the script and running it with the example image just gives me a blank readout. Someone else had the same problem here: https://www.autoitscript.com/forum/topic/174476-single-dll-file-for-ocr/#comment-1263034 but doesn't provide an explanation of how they fixed it. Has anyone else experienced this problem and know of a fix?
There has been many questions about using tesseract of late.
Here is a very basic example which works for me, along with the exact version of standalone tesseract executable and English language data used
I found it some time ago at a time I thought I needed it, I do not recall from where.
$ImageToReadPath = @ScriptDir & "\image.bmp" $ResultTextPath = @ScriptDir & "\Result" $OutPutPath = $ResultTextPath & ".txt" $TesseractExePath = @ScriptDir & "\Tesseract.exe" ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE) If @error Then Exit MsgBox(0, "Error", @error) EndIf MsgBox(0, "Result", FileRead($OutPutPath)) FileDelete($OutPutPath) Some Answers:
The files contained in the download, only support English language.
From the only documentation I got with this version...
Original Binaries and Source can be found here: http://code.google.com/p/tesseract-ocr/ I do not know where to get other languages support.
I do not know if there is a later standalone version.
I do not know why it does not read your image accurately.
It does not have a virus in it.
You can search the forums or internet to learn how to create / cut / copy / paste, or otherwise manipulate your own images.
