Hello, I would like to ask about OpenCV’s support for the CANN backend, particularly in image preprocessing, as I need to use many interpolation methods like the resize function. Could you please tell me which version of OpenCV began supporting CANN acceleration for the resize function? If it does support it, does it support the INTER_AREA scaling method and the INTER_LINEAR scaling method?Hello, I would like to ask about OpenCV’s support for the CANN backend, particularly in image preprocessing, as I need to use many interpolation methods like the resize function.

never heard of “CANN”.
you’re in luck, there’s a wiki page for it: Huawei CANN Backend · opencv/opencv Wiki · GitHub that also talks about opencv versions
and there is a cann namespace in the docs: OpenCV: cv::cann Namespace Reference
looks to me like you’d have to call those APIs explicitly, if you want to do image processing with them.
