# Create a directory to store frames if it doesn't exist frame_dir = 'frames' if not os.path.exists(frame_dir): os.makedirs(frame_dir)
video_features = aggregate_features(frame_dir) print(f"Aggregated video features shape: {video_features.shape}") np.save('video_features.npy', video_features) This example demonstrates a basic pipeline. Depending on your specific requirements, you might want to adjust the preprocessing, the model used for feature extraction, or how you aggregate features from multiple frames.
# Extract features from each frame for frame_file in os.listdir(frame_dir): frame_path = os.path.join(frame_dir, frame_file) features = extract_features(frame_path) print(f"Features shape: {features.shape}") # Do something with the features, e.g., save them np.save(os.path.join(frame_dir, f'features_{frame_file}.npy'), features) If you want to aggregate these features into a single representation for the video: shkd257 avi
