  1. 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
  2. #include <IE.au3> #include <Tesseract.au3> #include <MsgBoxConstants.au3> #include <Math.au3> #include <FileConstants.au3> #include <StringConstants.au3> #include <File.au3> #include <ScreenCapture.au3> #include <sound.au3> #Include <WinAPI.au3> #include <Date.au3> $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 EndIf EndIf Wend 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.
  3. I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR. Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results. An ideal hash key for this cache would be a checksum of the captured image. With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR. Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile(). But that's still slower than I would like, and it shouldn't be necessary. Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all. In order to do that, I need a way to dump a representation of the image into a string (or some equivalent). Then I could use the _Crypt_HashData() function against that string to create my cache hash key. Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing. This was the closest thing I found to what I'm trying to do. I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about. If someone could give me a shove in the right direction it would be a big help. Thanks!
  4. Hello all! With your help I have been able to conquer every problem I've faced thus far in using AutoIt, but I've come across something that I 1) don't fully understand and 2) am not sure how to even begin tackling. I have the following list box in a GUI that I am trying to automate that I cannot read any data from. I have discussed this in a previous thread and tried several solutions, but the conclusion was that OCR would probably be the best way to go. You can see the list info and the list box(the data has been edited out) below: I need to find a way to view the data in the list box and choose the user parameter(in this case, the correct library). There will also be instances where I will simply need to get data from another list and validate it it. I believe the major issue is that the list is populated at runtime(this was discussed in a previous thread) and that is why I cannot directly access the data in the list. I have viewed both of these threads: but am not able to full grasp how I should be using either of them. Unfortunately this means that I also don't really have a script to post at this point in time either. If anyone that has experience with this can help me out or point me in the right direction, that would be a huge help. This is the last piece of the puzzle for me and it has absolutely driven me crazy I am trying to incorporate everything into AutoItx4Java, but am prepared to run an executable for these portions if necessary. Thanks in advance for any help you might be able to give! I will do my best to get back to you with any questions as soon as I can.
  5. I have lot's of images like this http://postimg.org/image/uz24d8z27/ http://postimg.org/image/5isx6mc61/ i would like to crop the page number (the arabic number on the top of the page) so it would be something like this ... any ideas ?
  6. OCR = Optical Character Reading Hello all, I am theory crafting here for now and all help is appreciated First of all I would like to remind everyone that i am not a skilled programmer and I am even a slow and poor learner. so if you explain me something please make sure I can understand, I would really be thankful for that. 1. I have a program that allowed browse through a digital online brochure / stock and It always used to work perfectly with pixelchecksum() conversion to database and I got what I wanted but things have changed negatively for me. They Have changed the look of the digital brochure. 1. They have made fonts more transparent 2. They have made the font much much smaller often letters are 7pixels high and 5 pixels width for example the letter Afflicted looks like this; keep in mind that this is 1600% increased this image is originally 84x9 pix which is very small 3. They have added a pesky background which messes my autoit Pixelchecksum beyond useable So my while project / Program is halted to a stop and I already spend more then 1000 hrs in it I have to change my program I have done some decent analyzing on the screenshots / digital brochure and came to a conclusion that there is always enough RGB Difference between my font and background So it seems I need to proper filter it, Train it ( i do not mind spending lotsa time into it) My goal is to able to read text as quick as possible , therefor I am looking into my own personal lightweight OCR I would like it to able to read a page of 50 items of lets say average of 30/35 words each line and my goal is to achieve this under 500MS but i would not weep if it would take 1000 ms speed is very important to me, What would be best approach? making / creating a seperate .DLL or Exe for OCR and if I make a seperate exe or .DLL how does it transfer the information instantly between .exe (or is that impossible) it would be best for me that my autoit.exe does not waist time on trying to OCR, my autoit already; -------------------------------------------------------------------- handles onscreen actions (mousemovement), other calculations , Writing and retrieving to database, and interaction with a different program ------------------------------------------------------------------- for example my theory is as follow I make an extra ocr.exe or ocr.dll which either prepares out of itself the data upfront or does it when it is asked (having the ability on the fly and change it when needed during the process would be extremely nice because I can switch between speed and saving Resources if needed) question 1 = I am not sure yet how this can be transferred between ? 1. does it need to written in text file , 2. can it be saved in physical memory 3. does the ocr. saves itself in some array and gives it out on request from my autoit.exe Thank you for reading, I will show in a few hrs my theory how to basic program it for speedyness
