    • The postfix of video.
    • This parameter is a list.
  • Note that the number of elements in x_shift_range, y_shift_range, z_shift_range, traj_types and video_postfix should be equal.
  • specific: ''
    • The specific image name, use this to specify the image to be executed. By default, all the image in the folder will be executed.
  • longer_side_len: 960
    • The length of larger dimension in output resolution.
  • src_folder: image
    • Input image directory.
  • depth_folder: depth
    • Estimated depth directory.
  • mesh_folder: mesh
    • Output 3-D mesh directory.
  • video_folder: video
    • Output rendered video directory
  • load_ply: False
    • Action to load existed mesh (.ply) file
  • save_ply: True
    • Action to store the output mesh (.ply) file
    • Disable this option save_ply: False to reduce the computational time.
  • inference_video: True
    • Action to rendered the output video
  • gpu_ids: 0
    • The ID of working GPU. Leave it blank or negative to use CPU.
  • offscreen_rendering: True
    • If you're executing the process in a remote server (via ssh), please switch on this flag.
    • Sometimes, using off-screen rendering result in longer execution time.
  • img_format: '.jpg'
    • Input image format.
  • depth_format: '.npy'
    • Input depth (disparity) format. Use NumPy array file as default.
    • If the user wants to edit the depth (disparity) map manually, we provide .png format depth (disparity) map.
      • Remember to switch this parameter from .npy to .png when using depth (disparity) map with .png format.
  • require_midas: True
    • Set it to True if the user wants to use depth map estimated by MiDaS.
    • Set it to False if the user wants to use manually edited depth map.
    • If the user wants to edit the depth (disparity) map manually, we provide .png format depth (disparity) map.
      • Remember to switch this parameter from True to False when using manually edited depth map.
  • depth_threshold: 0.04
    • A threshold in disparity, adjacent two pixels are discontinuity pixels if the difference between them excceed this number.
  • ext_edge_threshold: 0.002
    • The threshold to define inpainted depth edge. A pixel in inpainted edge map belongs to extended depth edge if the value of that pixel exceeds this number,
  • sparse_iter: 5
    • Total iteration numbers of bilateral median filter
  • filter_size: [7, 7, 5, 5, 5]
    • Window size of bilateral median filter in each iteration.

    • Intensity term of bilateral median filter
  • sigma_r: 0.5
    • Spatial term of bilateral median filter
  • redundant_number: 12
    • The number defines short segments. If a depth edge is shorter than this number, it is a short segment and removed.

    • The thickness of synthesis area.
  • context_thickness: 140
    • The thickness of context area.
  • background_thickness_2: 70

    • The thickness of context area when inpaint second time.
  • discount_factor: 1.00
  • log_depth: True
    • The scale of depth inpainting. If true, performing inpainting in log scale. Otherwise, performing in linear scale.

    • The fraction of pixels to crop out around the borders [top, left, bottom, right].
