Computational Speed of Conversions

[JoshuaEbenezer]

This library is incredible but a lot of functions seem to be really slow. I've been using this for color space or EOTF conversions (BT2020<->BT709 or SMPTE2084<->Linear) and these take a few seconds for 4k images. Do you have any suggestions or plans to improve speed?

Hi @JoshuaEbenezer,

Yes this is acknowledged and last year, one of our GSoC projects was just about that, i.e. The Need for Speed. @OmarWagih1 created a repository to benchmark Colour and implemented support for Cupy in this PR: #625

It needs to be merged but requires me sourcing a good machine with Cuda.

Cheers,

Thomas
