So it works, but just need to rewrite nearly every API.

i just saw it, i will try to implement what i can and open a pr to this pr branch, can we spilt the modules so i handle some and you handle some to avoid we both implementing the same things?

also whats the easiest module i can follow as a reference since this pr has the alot of changes, so an easy module to follow will be the best option

Sure, just create a new branch from async branch

also whats the easiest module i can follow as a reference since this pr has the alot of changes, so an easy module to follow will be the best option

For now I just implemented calib3d and imgcodecs, I think imgcodecs is the easiest, just several API in it, but remember to take a loot at core/types.h, in which many basic definitions inside it.

@abdelaziz-mahdy I have added async version of SVD, hope you are not doing the same module, may I ask which module are you working (or planning working) on?

Besides, if you finish some module, please open a PR to async branch.

[abdelaziz-mahdy]

I think dnn or objdetect, and if I faced any problem will let you know

For pr, deal will do so
