Per-image-key undo/redo stacks of annotation-dict snapshots.

One image plus the specs for its instances, loaded lazily. ``image_loader`` returns an RGB ``uint8`` array (matching what ``sam_utils._qimage

A custom QLabel for displaying images and handling annotations.

Minimal stand-in for QMouseEvent — only modifiers() is read.

Minimal QMouseEvent stand-in — only modifiers() is read by the helpers.

Fine-tunes a SAM 2 mask decoder (optionally image encoder) on user instances. Mirrors ``YOLOTrainer``'s signal/stop surface so the controller

Shows the phrase list for whichever class row is currently selected in ClassThresholdTable. The class name itself is always the first phrase

A QTableWidget where each row = one class. Columns: Class Name | Box thr | Text thr | NMS thr The spinboxes are embedded directly in the

Application-wide event filter that lets Enter / Escape accept or reject pending DINO temp_annotations regardless of which widget has focus. Wi

In-process Grounding DINO wrapper with a cached model.

Merge per-image COCO JSONs into train.json and val.json.

Mutates ImageLabel's `temp_eraser_mask` and `is_erasing`. The commit path (OpenCV polygon clipping) is moved byte-for-byte from the pre-Phase-

Minimal stand-in for ImageAnnotator with the state the filter reads.

Raised when ``_run_sync`` is re-entered before the first call returns. See ``_run_sync`` for the full story. Callers that drive inference fro

Mutates ImageLabel's `temp_paint_mask` and `is_painting` so other code paths (notably `check_unsaved_changes` callers and paint-mask rendering

Mutates ImageLabel state fields (`current_annotation`, `temp_point`, `drawing_polygon`) directly — those fields are still read by AnnotationCo

Mutates ImageLabel state fields (`start_point`, `end_point`, `current_rectangle`, `drawing_rectangle`) directly. Those fields stay on the widg

Modal config for a fine-tuning run. Read results via :meth:`get_config`.

Runs a fine-tuning job off the GUI thread. Emits the result dict on success or the exception's string on failure (same contract as YOLO's ``Tr

Runs Ultralytics SAM 2 in-process with a cached model.

Runs a callable on a background thread. Captures both the return value AND any exception raised, so ``_run_sync`` can re-raise on the calling
