Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| probImage | NPARRAY,IMAGE,MASK | Back projection of the object histogram. See calcBackProject. Accepts a ComfyUI IMAGE/MASK directly (frame 0 of a batch) or an NPARRAY. Arithmetic ops (add, multiply, etc.) process the full IMAGE batch when both inputs have the same batch size. | |
| window_x | INT | 0-2147483648–2147483647 | Rectangle top-left corner X in pixels. |
| window_y | INT | 0-2147483648–2147483647 | Rectangle top-left corner Y in pixels. |
| window_w | INT | 00–2147483647 | Rectangle width in pixels (>= 0). |
| window_h | INT | 00–2147483647 | Rectangle height in pixels (>= 0). |
| criteria_type | COMBO | max count or epsilon (whichever first) | When to stop iterating: after max_count iterations, when the change drops below epsilon, or whichever comes first. |
| criteria_max_count | INT | 301–2147483647 | Maximum iterations (ignored when 'epsilon only'). |
| criteria_epsilon | FLOAT | 0.000–1e+38 | Target accuracy / smallest change worth continuing for (ignored when 'max count only'). |
Outputs (2)
| Name | Type | Description |
|---|---|---|
| rotatedRect | CV_ROTATED_RECT | - - - Rotated rectangle ((center_x, center_y), (width, height), angle in degrees) - wire it into cv2.ellipse's box, cv2.boxPoints or cv2.rotatedRectangleIntersection. |
| rect | BOUNDING_BOX | - - - A cv2 Rect as core BOUNDING_BOX data ({x, y, width, height}, nested one group per frame) - feed 'Crop By Bounding Boxes', 'Draw BBoxes', or 'CV Split Tuple' for x/y/w/h. |
