7ad91c15 - Added antialias flag to interpolate (CPU only, bicubic) (#68819)
Commit
2 years agoAdded antialias flag to interpolate (CPU only, bicubic) (#68819)
Summary:
Description:
- Added antialias flag to interpolate (CPU only)
- forward and backward for bicubic mode
- added tests
Previous PR for bilinear, https://github.com/pytorch/pytorch/pull/65142
### Benchmarks
<details>
<summary>
Forward pass, CPU. PTH interpolation vs PIL
</summary>
Cases:
- PTH RGB 3 Channels, float32 vs PIL RGB uint8 (apples vs pears)
- PTH 1 Channel, float32 vs PIL 1 Channel Float
