Visual inspection

The viewer overlays boxes and masks for quick spot checks. For mask datasets, it blends the segmentation mask over the image.

Launching the viewer

argus-cv view /datasets/retail

View a specific split

argus-cv view /datasets/retail --split val

Adjust mask opacity

argus-cv view /datasets/roads --opacity 0.3

Controls

  • Right arrow or N: next image
  • Left arrow or P: previous image
  • Mouse wheel: zoom in or out
  • Drag: pan while zoomed
  • R: reset zoom
  • Q or Esc: quit
  • T: toggle annotations or mask overlay

Notes

  • The viewer uses OpenCV; it requires a desktop environment.
  • If the window does not open, make sure you are not on a headless server.
