cap.release() print(f"Extracted {frame_count} frames.") Now, let's use a pre-trained VGG16 model to extract features from these frames.

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. import cv2 import os import numpy as np

while cap.isOpened(): ret, frame = cap.read() if not ret: break # Save frame cv2.imwrite(os.path.join(frame_dir, f'frame_{frame_count}.jpg'), frame) frame_count += 1
