Re: [gentoo-user] extracting text, numbers from screencasts
On 04/08/16 11:30, Helmut Jarausch wrote: On 04/08/2016 03:26:53 PM, hw wrote: Hi, what would be the best approach to extract data from a screencast? The task is to acquire some data from the display of a GUI program used interactively by a user. There are a couple 'fields' (as in "designated areas of the display") in which the relevant data is being displayed while the program is being used. The acquired data needs to be entered into a mysql database, preferably as soon as possible. (The program needs windoze, and the sources are unavailable :( ) The idea is to make a screen recording and postprocess the recording with some sort of OCR software. This might require using ffmpeg (or the like) to create a single image from each frame of the recording; then treat each image with an OCR software to get the interesting data which can then be entered into the database. Data to extract is mostly numbers. The relevant fields can be expected to be either filled or empty. The FPS rate of the recording can be kept reasonably low, like 1 FPS, or perhaps even less, depending on how frequent the relevant fields change. Using tesseract comes to mind, but after reading that "Tesseract's output will be very poor quality if the input images are not preprocessed to suit it: Images (especially screenshots) must be scaled up such that the text x-height is at least 20 pixels,[12] any rotation or skew must be corrected or no text will be recognized, low-frequency changes in brightness must be high-pass filtered, or Tesseract's binarization stage will destroy much of the page, and dark borders must be manually removed, or they will be misinterpreted as characters."[1] I'm even more doubtful that this would produce usable results with sufficient reliability. So what might be the best way to get text/numbers out of what a program displays? [1]: https://en.wikipedia.org/wiki/Tesseract_(software) I can't help with Gentoo. Try to find an old (free) version of FineReader which runs under wine. If you do it only occasionally, transfer the image to an Android phone where there a good and cheap OCR apps, even FineReader. I had some surprisingly good experience with tesseact in digitizing photographed pages of an old book recently. So I gave it a try today with a cropped screenshot of thunderbird. $ convert scrsht.png -type Grayscale -filter point -resize 300% -normalize upscaled.png $ tesseract -l eng upscaled.png out $ less out.txt convert is from media-gfx/imagemagick-6.9.0.3 tesseract is app-text/tesseract-3.04.00-r2 Here are my findings: Any graphical elements sized similar to an character appear as strange letters. Recognition of serif fonts was better than sans-serif fonts, even at smaller font size. Text which can be spell-checked was nearly perfectly recognized. Gentoo-specific words like "GLSA" and "NVMe" was not correctly recognized. Selected text (white on blue background) was poorly recognized. Dates were not recognized correctly. Times were correctly read. "convert" time for a initial screenshot size of 956 x 639 pixels was 0.4 seconds. "tesseract" time was a little more than 6s on an Intel(R) Core(TM) i7-4710MQ CPU @ 2.50GHz, without opencl. The image conversion and tesseract ocr could easily be scripted. In short I would say that the following steps would help with tesseract: Avoid GUI with a lot of graphics. Try to screenshot just the relevant areas. Increase GUI font size. Configure GUI to use a well known serif font, or train tesseract for the specific font used. Configure GUI to use high contrasts, avoid colors which get converted to gray. Tesseract time could be improved by enabling opencl. I would be interested to hear about your findings with numerical data, and which approach finally works for you. Urs
