+## `train/pose-1st-iteration/` (113 images + 2 CSVs)
+
+Earlier (first-pass) capture and processing of the same static pose images later finalized under `train/pose/`. A few images were renamed in the final pass (e.g. `stand-knee-up3.jpg` here is `stand-knee-up3-ocluded.jpg` in `train/pose/`), and the two CSVs below are this first pass's classifier output - not byte-identical to the final versions in `train/pose/` since the underlying feature values differ slightly between passes.

+First-pass MediaPipe-derived static-pose features for all 113 images (same 13-column schema as `train/pose/features_output.csv` - see column descriptions). Superseded by, but not identical to, the final-pass version in `train/pose/`.
+
+**`train/pose-1st-iteration/features_output_predicted.csv`**

+## `train/pose/` (113 images + 11 CSVs)
+
+Final-pass captures of the 113 static pose images (the versions the dissertation's headline results are computed from), plus the derived feature/classifier CSVs. Most images are identical to `train/pose-1st-iteration/`; a few were renamed to describe the pose more precisely (e.g. `stand-knee-up3.jpg` became `stand-knee-up3-ocluded.jpg`).
+
+**`train/pose/features_output.csv`**
+Final-pass MediaPipe-derived static-pose features for all 113 images (13 columns - see the column descriptions). This is the primary feature file; the model1_/model2_ variants alongside are rule-variant comparisons, and an earlier pass lives in `train/pose-1st-iteration/`.
+
+**`train/pose/features_output_predicted.csv`**
+`features_output.csv` plus the rule-based classifier's `label`/`predicted_label` columns - the file behind the 74.3% static-posture accuracy shown in the demo notebook.
+
+**`train/pose/grouped_kmeans_static_pose_boundingbox_data.csv`**
+K-means cluster summary (min/max/mean/count of pose bounding-box aspect ratio per cluster) across the 113 images. Note: pandas multi-index export - data row 0 holds the sub-column labels ('min'/'max'/'mean'/'count'), skip it when loading.
+
+**`train/pose/grouped_static_pose_boundingbox_data.csv`**
+Overall mean pose bounding-box aspect ratio, relative width, and relative height across the 113 images. Same multi-index export quirk: data row 0 holds the sub-column label ('mean').
+
+**`train/pose/model1_features_output.csv`**
+Static-pose features computed with rule-variant 1 of the feature extractor (the `model` parameter of `get_features` in the ai-posture-monitor package); kept for comparison against the primary output.
+
+**`train/pose/model1_features_output_predicted.csv`**
+`model1_features_output.csv` plus the classifier's `label`/`predicted_label` columns.
+
+**`train/pose/model2_features_output.csv`**
+Static-pose features computed with rule-variant 2 of the feature extractor - the variant the primary `features_output.csv` is based on.
+
+**`train/pose/model2_features_output_predicted.csv`**
+`model2_features_output.csv` plus the classifier's `label`/`predicted_label` columns.
+
+**`train/pose/static_pose_boundingbox_data.csv`**
+Per-image pose bounding-box geometry (frame size, aspect ratio, relative width/height) computed from the focused keypoint subset (shoulders/hips/knees/ankles).
+
+**`train/pose/static_pose_boundingbox_data_all_keypoints.csv`**
+Per-image pose bounding-box geometry computed from all 33 MediaPipe keypoints (vs. the focused subset used in `static_pose_boundingbox_data.csv`).
+
+**`train/pose/static_pose_boundingbox_data_bounding_box_size_predicted.csv`**
+Bounding-box geometry plus ground-truth `label` and a bounding-box-aspect-ratio-only posture `predicted_label` - the fallback classifier for images where MediaPipe landmark detection fails (e.g. some lying/occluded poses).
+
+**`train/pose/bend-2.jpg`**
+Subject bending at the waist (variation 2).
+
+**`train/pose/bend-backwards.jpg`**
+Subject bending at the waist, bending backwards.
+

+## `train/results of static pose classifier on training videos/`
+
+Per-frame output of the same rule-based static-posture classifier behind `features_output_predicted.csv`, run across motion-triggered frames of the 3 training videos. This run predates the fall-detection/temporal-smoothing layer described in the project README, so these files cover static posture classification only (no `fall`/`fall_watch`/`smooth_prediction` columns - see column descriptions for the full per-column schema).
+
+**`train/results of static pose classifier on training videos/hr_fall_detection_static_pose_class_on_video_1_results.csv`**
+Per-frame output for `hr_fall_detection_1.mp4`: 807 motion-triggered frames (frame indices 28-1508); a pose was successfully detected and classified on 132 of them (16%), with predictions of stand/sit.
+
+**`train/results of static pose classifier on training videos/hr_fall_detection_static_pose_class_on_video_2_results.csv`**
+Per-frame output for `hr_fall_detection_2.mp4`: 5,741 motion-triggered frames (frame indices 1-6200); a pose was successfully detected and classified on 4,676 of them (81%), with predictions of sit/stand/lie.
+
+**`train/results of static pose classifier on training videos/hr_fall_detection_static_pose_class_on_video_3_results.csv`**
+Per-frame output for `hr_fall_detection_3.mp4`: 8,743 motion-triggered frames (frame indices 52-11826); a pose was successfully detected and classified on 8,108 of them (93%), with predictions of sit/stand/lie.

+
+Note: this matches the live Kaggle dataset's current structure/paths. The local OneDrive copy of `train/pose-1st-iteration/` nests the two CSVs under a `results/` subfolder, and the local per-frame results files are named `static_pose_class_on_video_hr_fall_detection_N_results.csv` (reversed word order vs. Kaggle's `hr_fall_detection_static_pose_class_on_video_N_results.csv`) - same content, different path/name. This divergence between the local copy and the published dataset was flagged earlier and deferred; the descriptions above use Kaggle's actual paths.
