Working with images, java?

Question

Java

How are different photo filters implemented on Instagram, and how to make something similar to java? Is there a special library for this? Or work directly with the RGB image array?

Answer 1

Of course you will lose performance. Java isn't very productive at number grinders, which is what image processing is all about.
Native code in this regard wins because of the ability to use vector instructions.
But since you are asking such a question at all, then I would advise you to write everything in pure Java to begin with. Get easy assembly and convenient debugging.
You will think about optimizations later.
Well, the library is a hell of a lot. Search on github.
