Where is it better to do photo processing server or client?

Question

Java

The essence is this: a picture is taken in a mobile application, then you need to get the text from this picture for further work with it. Question: where is it better to receive text in a mobile application and send text to the server or send photos to a server and receive text there?
And what other library would you recommend for text recognition in java?

Answer 1

first you need to decide under what conditions the application will work: in an office with Wi-Fi or in a tmutaraka without a connection. In the second case, there is nowhere to go, you need to recognize it on the device and then synchronize with the server. Naturally, these are extreme cases, you need to look at the real use cases of your application. Abbyy
has the finest frameworks for doing this.

Answer 2

Immediately the question is: Where do you MANDATORY need to use the text from the image: on the client or on the server?
If it is on the server, it is easier to recognize the image on the server, otherwise - no options: recognition will need to be implemented within the application itself, which is much more complicated and resource-demanding and, accordingly, will consume more precious battery power during algorithmic miscalculations.
