"""Main window: open a **project** and inspect what the detector found.
|
||
|
||
A project is a folder (``project.json`` + ``frames/`` + ``detections.json`` +
|
||
``collections/``) — see ``core/project.py``. The per-project settings (detector,
|
||
model, threshold, restore engine) live in ``project.json``; the global
|
||
``settings.json`` only seeds defaults for new projects.
|
||
|
||
Layout: a toolbar (new/open project · from-video · detector · model · calc-frame ·
|
||
detect-all · threshold), then a splitter with three panes — left: collection
|
||
controls + the file list; center: the image with overlays; right: a detail table
|
||
of every detection. Collection controls sit by the file list (they act on its
|
||
selection), keeping the toolbar to detection/entry actions only.
|
||
|
||
Viewing and detecting are decoupled, so browsing a big project stays instant even
|
||
with a slow (CPU) detector:
|
||
- selecting a file just **shows** it (with its cached result, if any);
|
||
- **double-clicking** a file, or "Рассчитать кадр", runs the detector on it;
|
||
- "Детектировать все" runs the whole project.
|
||
Both project loading and detect-all show a progress bar. Results are cached in the
|
||
project; switching detector/model clears the cache.
