Collect labelled summaries
Assemble video clips with human-selected keyframes or timestamps and store frame-level metadata (time, scene, shot boundaries).
Summarise videos into keyframes. Assess temporal and coverage quality.
Video summarization selects representative frames or short clips to communicate the important content of a longer video. Key challenges include temporal redundancy, preserving event coverage, handling camera motion and choosing summary length that matches user needs.

Video summarization selects representative frames or short clips to communicate the important content of a longer video. Key challenges include temporal redundancy, preserving event coverage, handling camera motion and choosing summary length that matches user needs.
A possible application: produce a short highlight reel for long surveillance or lecture footage to speed human review. This proposed extension should keep a human reviewer in the loop and not be used for unattended critical decisions.
Assemble video clips with human-selected keyframes or timestamps and store frame-level metadata (time, scene, shot boundaries).
Use OpenCV or a pretrained CNN to extract per-frame embeddings and shot boundaries before selecting representatives.
Train a model that ranks frames or predicts importance scores, and validate using precision/recall of selected keyframes and temporal coverage metrics.
Export an inference pipeline that returns a ranked list of frames plus a preview interface and confidence thresholds for human review.
The supplied starter loads the sklearn digits image dataset, splits it, trains a RandomForestClassifier on static 8x8 digit images, prints a classification report and plots a confusion matrix. It does not load video frames, compute temporal features, select keyframes, or use OpenCV or sequence models.
digits = load_digits()
X_train, X_test, y_train, y_test = train_test_split(
digits.data,
digits.target,
test_size=0.25,
random_state=42,
stratify=digits.target,
)
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)The starter uses the sklearn digits dataset (handwritten digit images) and a RandomForest classifier; it contains no video data, no temporal modelling or shot/keyframe selection logic, and therefore does not implement video summarization.
Proposed extension: convert videos to frame sequences, extract per-frame embeddings with a pretrained CNN, detect shot boundaries, and train a ranking model to select representative keyframes or short clips for a summary.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
