Support BICUBIC interpolation for image resizing

Open JarnoRFB opened this issue 1 year ago • 2 comments

How can this feature be used?

Bicubic image resizing is useful when requiring a resizing method that preserves higher quality, e.g. for object detection, and is implemented as a basic operation in Frameworks such as PyTorch.

Describe alternatives you've considered

Using bilinear interpolation.

This seems like the exact same request as #1747.

@JarnoRFB - how is this different than that?

@TobyRoseman Not entirely sure. #1747 talked to about the upsampling and I am particularly interested in downsampling. This is beyond my Pytorch knowledge, but could be that downsampling is supported via the upsample_bicubic2d operator.
