Inspect Images

The image inspection tool allows users to explore both the visual appearance and the underlying sensor measurements contained in GONet observations.

Unlike conventional image viewers, GONet Wizard can display the individual Bayer channels recorded by the camera sensor, making it possible to inspect both processed imagery and the underlying RAW data.

The tool is designed not only for image viewing, but also for comparison and exploration across multiple observations.

Typical Uses

The image inspection tool is commonly used to:

  • Evaluate image quality.

  • Compare multiple observations.

  • Identify saturated regions.

  • Inspect Bayer channels individually.

  • Verify focus and exposure.

  • Explore image features before performing measurements.

Supported Files

Image inspection works with original RAW .jpg GONet images, as well as with derived products like converted .tiff files.

Multiple Files

Multiple images can be displayed simultaneously within the same viewer.

Each selected file is displayed in its own section and can be inspected independently or compared against other observations.

When several files are loaded, the viewer becomes a powerful comparison tool for studying changes between observations, evaluating image quality, or tracking the evolution of a scene over time.

Warning

GONet images contain both JPEG and RAW Bayer data and can be relatively large (approximately 20 MB per file).

Loading a large number of images simultaneously may significantly increase memory usage and reduce responsiveness.

Channel Selection

The displayed channels can be selected by the user.

By default, the viewer displays the Blue, Green, and Red Bayer channels, but alternative channel combinations may also be displayed depending on the selected visualization mode.

The same channel selection is applied to all loaded images.

When multiple files are displayed simultaneously, identical channels are aligned in the same column. This makes it easy to compare the same Bayer channel across multiple observations.

For a detailed discussion of channels, see channels user guide.

Interactive Navigation

The viewer uses standard Plotly interactions.

Zooming

To zoom into a region of interest:

  1. Click and drag on the image.

  2. Release the mouse button to zoom to the selected region.

To reset the zoom:

  • Double-click anywhere within the image.

Panning

After zooming, the image may be panned using the standard Plotly toolbar controls.

Inspection

The viewer supports interactive exploration of image data, allowing users to quickly move between large-scale image features and fine pixel-level structure.

Zoom Synchronization Modes

When multiple images and channels are displayed, the viewer can synchronize zoom operations across related plots.

Three synchronization modes are available.

All

The default mode.

Zooming or panning any image updates every displayed channel of every loaded file.

This mode is useful when comparing multiple observations of the same target.

Same File

Zoom operations are synchronized only between channels belonging to the same image.

This mode is useful when comparing Bayer channels within a single observation while allowing different files to remain independent.

Independent

Zoom operations affect only the selected plot.

No synchronization is performed.

This mode is useful when examining different regions of different images simultaneously.

Accessing the Tool

The image inspection tool can be accessed through both the graphical user interface and the command-line interface.
