What is a good kotlin Multiplateform library for image processing like cropping, resizing, normalize, toTensor ?

Is Korim + KMath + MultiK what I need ?

[altavir]

I never worked with image processing. I think there are some obstacles on this path. Each platform has its own "native" image format, so we need to abstract it first. If you can draft a design document for such thing, it would be helpful.

Unfortunately, Multik is not yet multiplatform. We are planning this in the next release.
@zaleslaw tried Multik for image preprocessing in his KotlinDL library.

@altavir My needs are pretty basic I think, what kind of design document would help? An example of an abstraction for images like an interface ?

[Alexandre Brown]

@Pavel Gorgulov Great, can you share any roadmap or rough release "date" for multiplatform?

[altavir]

Sadly, we do not have manpower to do a proper roadmap yet.

[zaleslaw]

The most problem to make a good resizing, it requires bicubic or bilinear interpolation under the hood. When we talk about multiplatform, what platform do we really discuss?

[zaleslaw]

Cropping, normalizing and to tensor could be easily written, but resizing is not so easy thing

[altavir]

We actually have multiplatform 1D interpolation already in kmath (both linear and spline) and it is not that hard to add 2D

[zaleslaw]

So, it could be a solution))

[Alexandre Brown]

@zaleslaw Ideally JVM and native

[altavir]

Native is hard

[zaleslaw]

Native and JVM, is it for backends?

[altavir]

KMath does support native. Even for tensors, but I can't say we've tested it well.

You can see open tasks in Multik, many of them will be included in the next release. After December 8, a detailed roadmap with a release date will be collected.
