3. 参数调整(可选):
|
||||
- `points_per_side`: 网格密度(默认 32,越大越精细但越慢)
|
||||
- `pred_iou_thresh`: IOU 阈值过滤低质量 mask
|

- `stability_score_thresh`: 稳定性阈值(默认 0.95)

**医疗/低对比度场景调优建议**
|
||||
|
||||
在处理医疗手术图像等低对比度、边界模糊场景时,Auto Segmentation 容易因过滤过严而产生"角落碎块"(只保留高对比度杂色,漏掉目标器官)。遇到此现象时请重点调整以下两个参数:
|
||||
|
||||
| 参数 | 当前问题 | 建议修改 |
|
||||
|:---|:---|:---|
|
||||
| `stability_score_thresh` | 默认 0.95 要求过高。手术灯光反光、组织颜色接近,AI 很难在全图点阵下获得 95% 稳定性的遮罩,导致宁缺毋滥、滤掉模糊器官 | **降至 0.85 ~ 0.90** |
|
||||
| `points_per_side` | 默认 16 意味着全图只撒了 256 个探测点。对于 2560×1440 等高分辨率医疗画面,点阵空隙太大,容易漏掉细小器械或解剖结构 | **提高至 32 或 64** |
|
||||
|
||||
4. 输出:`mask`、`segmented_image`、`bbox`
|
||||
|
||||
**此时你可以先点击「运行」测试单帧分割效果。**
