Summary

This PR includes:

  • Update transforms to OTX's
  • Check performance for reproducibility
    • before performance is from after in Recipe refinement (det, iseg, r-det, sseg, vpm, zsl) #3712
      before : 746d07e | after : 2e32819

      segnext_s before 0.91 0.91
      after 0.90 0.90
      segnext_t before 0.90 0.89
      after 0.89 0.88

**NOTE
When using RandomResize + RandomCrop + Pad (mmseg pipeline) instead of RandomResizedCrop (current, torchvision pipeline), it seems that sometimes very small GT region was extracted like below figure and it significantly affected training performance, especially segnext_t (test/Dice : 0.46 and export/Dice 0.45). Due to this issue, use RandomResizedCrop instead.
