Is there any OCR software that can reliably copy the text in a jpg/png image?
This is a much moreplex question and will require more data from you. To expect any single software to be able to reliably OCR from any jpg or has s. You should write up a full specification of what you want to do and reach out to some ABBYY partners or other OCR businesses such as OpenText or Kofax and review solution ideas with a professional.

How can I extract text from a PNG image using Python?
As others have mentioned pytesseract is a really sweet tool but doesn work so well for dirty data e.g. street signs in a photo or overlayed on a landscape ) and draw a bounding box around the shapes Rescale all bounding boxes to the resolution of the CIFAR-1 dataset (2x2 pixels iirc) and convert to grayscale Feed the bounding boxes to the classifier you trained in step 1 All bounding boxes the classifier predicted to be fro the 74k Chars dataset is likely to be a character in the photo if it predicts the bounding box is part of CIFAR-1 drop the sample If need be widen bounding boxes labeled as 74k Chars that are close together since theyre likely part of the same work or phrase (or just lower threshold on the contrast shift detector so it detects ONE bounding box for the whole word then do second step detection within that one to detect individual chars Now youre done you have groups of detected characters from the s 813 85 s. There are tons of great articles books and posts about different ways to do any and all of the steps so happy coding!
How can I convert this flat text file into a PNG image? ...
What do you mean by flat file?nIf youre meaning a simple file - *.txt 1. Select and copy the and paste it as in any processor - Paint or Photoshop - document and Save as *.png .norn 3. Open it in a word processor - MS Word - Export a PDF Document open PDF in Photoshop and Save as *.png .

How can I convert a grayscale image (.png, .tif, .jpg, etc.) to a text (ASCII) x-y array with one z-value for the intensity of each pixel? Ideally, this would be a Unix command line tool.
Well you need to read the target library for this; it would take a rather long time to write your own. For PNG I can rmend LodePNG . Doing this for a multitude of file s makes it rather more difficult. Consider writing a tool that uses an existing program to convert images to (say) PNG. Then convert RGB values to greyscale. The simplest way would be to take the mean of all three; a weighted average will look better though. Then output to a file. I assume you can use some kind of programming language this should be easy. Alternatively read up on the Netpbm format s which is essentially the file you describe and programs probably exist that can do the conversion for you in themand line. I found myself wanting something to do the reverse - PPM to PNG - and couldn't find an appropriate program to do it so I wrote one myself during a car journey. It's fun. I meant to put it on GitHub leave ament if you want me to put it up there.
