User Interface#

To open the application the GUI, go to http://localhost:8080 in your browser. You can change the address with make up UI_HOST_PORT=9090 and print the LAN URL with make up and make run to be able to open the app from a different computer in the same network.

All on-screen data is driven by a single Server-Sent Events stream at /api/events (~1 Hz snapshot). There is no client-side state polling. The rendered video appears in a native pop-up sink launched by the pipeline container when display mode is enabled.

Here is a detailed description of the layout:

Left column

Notes

Source section

local form state → POST /api/start payload

Select file or basler and source argument (path / serial).

Device section

local form state → POST /api/start payload

Select runtime target (GPU / CPU / NPU).

Session controls

POST /api/start, POST /api/stop, POST /api/reset

Start/Stop/Reset from the accordion instead of toolbar/modal flow.

Right column — Pipeline Performance accordion

Below the table:

  • End-to-end summary bar — pipeline FPS · sample count · uptime · source kind.

  • Model & Input block — model name, precision (FP16 OpenVINO IR), task/dataset (Polyp Detection on ColonDB), video source resolution (e.g. 1080p H.264 (looped)), model input tensor size (640x640), and the runtime device.

Right column — Platform accordion

Live CPU / GPU / NPU utilization from intel-npu-info and nvidia-smi-style samplers, refreshed on every SSE snapshot.
