  • Run stitching in the preview mode. Works faster than usual mode, but output image will have lower resolution.
  --try_gpu (yes|no)
  • Try to use GPU. The default value is 'no'. All default values are for CPU mode.

Motion Estimation Flags:

• --work_megapix <float>

  • Resolution for image registration step. The default is 0.6 Mpx.

  --match_conf <float>

  • Confidence for feature matching step. The default is 0.65.

  --conf_thresh <float>

  • Threshold for two images are from the same panorama confidence. The default is 1.0.
  --ba (no|ray|focal_ray)
  • Bundle adjustment cost function. The default is 'focal_ray'.
  --wave_correct (no|yes)

Compositing Flags:

• --warp (plane|cylindrical|spherical)
  • Warp surface type. The default is 'spherical'.

  --seam_megapix <float>

  • Resolution for seam estimation step. The default is 0.1 Mpx.
  --seam (no|voronoi|gc_color|gc_colorgrad)
  • Seam estimation method. The default is 'gc_color'.

  --compose_megapix <float>

  • Resolution for compositing step. Use -1 for original resolution. The default is -1.
  --expos_comp (no|gain|gain_blocks)
  • Exposure compensation method. The default is 'gain_blocks'.
  --blend (no|feather|multiband)
  • Blending method. The default is 'multiband'.

  --blend_strength <float>

  • Blending strength from [0,100] range. The default is 5.
