A typical echogram analysis output is echogram "regions" - these are polygons that mark the boundaries of specific targets (e.g., fish species). To enhance usability, we want to build a Region Browser feature that allows users to navigate through identified regions (generated by ML models or drawn manually) in echogram data. This requires pulling the right echogram section (typically based on time) to display with the corresponding regions.
The Region Browser should enable users to:
- Step through all available regions sequentially
- Select a specific region from a dropdown menu
- Display the relevant echogram section with the corresponding polygon overlay
An initial concept sketch of the Region Browser is provided below:
