Inference Guide

  • Navigate to your script directory: 
      cd $SAPIENS_LITE_ROOT/scripts/demo/[torchscript,bfloat16]
  • For normal estimation (uncomment your model config line): 
    ./normal.sh

Define INPUT for your image directory, SEG_DIR for the .npy foreground segmentation directory (obtained from body-part segmentation) and OUTPUT for results.
The predictions will be visualized as (.jpg or .png) files to the OUTPUT directory as [image, surface normal]
Adjust BATCH_SIZE, JOBS_PER_GPU, TOTAL_GPUS and VALID_GPU_IDS for multi-GPU configurations.
