"""Main window: open a folder of images and inspect what the detector found.
|
||
|
||
Layout: a toolbar (open folder · detector · model · calc-frame · detect-all ·
|
||
threshold), then a splitter with three panes — the file list (left), the image
|
||
with overlays (center), and a detail table of every detection (right).
|
||
|
||
Viewing and detecting are decoupled, so browsing a big folder 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 folder.
|
||
Both folder loading and detect-all show a progress bar. Results are cached;
|
||
switching detector/model clears the cache.
