Make OCR reading faster( Image To Text )

Good Day, I can run OCR reading perfectly fine using Scott H Tech’s Plugin ( https://scotth.tech/plugin-imageToText )

One thing I want to fix is its speed on reading. How can I make it instantaneous on reading? For Example when I write V. At .1sec the letter “V” will return to me as a response. Thanks in advance

OCR is a very complex process. You might try cropping the image and making it smaller (use jpg). .1 seconds is really fast I don’t know if it is possible, especially on slower android devices. I don’t use timers or set times for the process, when it is done I send the results immediately to you code to handle.

Any Gesture plugin that I can use that is instant?

?

I wanted my app to have a gesture feature like, When I draw a letter “C”, it will give me a return of “C” as a response. The one i’m using now, is okay, but I can’t seem to use it cause it pauses the app, and it’s not good for a game. Any Gesture plugin that you can suggest, that when I draw a letter “C”, in an instant it will return to me “C” as a response.

Or is it any other way to limit the letters to match in this plugin? like I only want to detects vowels. Thanks in advance

#7

I don’t know of any marketplace plugins that could do exactly what you would want to do. I have not tested my plugin with handwriting so I don’t know how great the results will be.

#8

Anyway to limit the letters/words to search in your plugin? like search only the letters and numbers 1-9?

On android this should be possible you just need to find tess file that only detects what you want. On iOS unfortunately the tess file have to be embedded with the plugin, the only way to add your own custom Tess file would be corona native.

Sorry new on this, what is a tess file?

#12

can I use the traineddata_fast?

#13

You should be able to use any .traineddata file on android, see above for iOS

#14

It crashes when I use the traineddata_fast eng version

#15

You should launch a bug report then https://docs.google.com/forms/d/e/1FAIpQLSf-V3z-V3FZ5y9Sb19cxVfjx7fSRV9HIbpAGptN7DaY3Ki_DA/viewform

Sorry - just came across this - Scott - can you confirm that this plugin doesn’t work in the simulator, only on device?

I’ve purchased it but am getting a non-supported platform message in the simulator.

Assume this is why, but just wanted to check I’m not missing something as testing in simulator would be helpful.

Thanks.

yep, only works on device
