jimg Posted April 15, 2022 Share Posted April 15, 2022 I have a small (20x14) "unknown" image (from a _screencapture) that I need to match against a collection of maybe 20 possible images. Tesseract and UWPOCR don't work reliably for unknown reasons. What would be ideal is that I could return a match quality value, and pick a value that works. I have to do this many times and using command line calls for each trial would be slow. I presume I can brute force the image into an array and do a pixel by pixel comparison, but I'm hoping someone has already solved this problem. I read about imagesearch which may be the solution, but it may be overkill at the cost of speed. Link to comment Share on other sites More sharing options...

Solution Nine Posted April 15, 2022 Solution Share Posted April 15, 2022 (edited) Have you tried PixelChecksum ? If that works, you could simply save the checksums into an ini file (for example) and just compare numbers, it would be really really fast ... edit : Could you also add a zip containing the images, so we can have a look on how to achieve it ?

jimg Posted April 15, 2022 Author Share Posted April 15, 2022 I'll give the checksum a shot. I don't have my library of images to upload created yet, since I didn't want to go down a blind alley. Link to comment Share on other sites More sharing options...
Nine Posted April 15, 2022 Share Posted April 15, 2022 Since you are testing some options, you must have an example to show us, would be easier to assist you if we know what we are talking about.

jimg Posted April 16, 2022 Author Share Posted April 16, 2022 In my app, the images are very repeatable. Dhash might allow it to work across platforms that have different Cleartype settings, and if the users find that desirable, I'll look into it. This whole thing gets used for a few weeks, then discarded, The Pixel Checksum works great and is orders of magnitude faster than struggling with tesseract.
