Project 6: Multimodal Video Analysis and Summarization

Step 4: Perform Video Frame Analysis

Analyze the extracted frames using a vision transformer like VideoMAE (Video Masked Autoencoder). This powerful model processes video frames by dividing them into patches and applying self-attention mechanisms to understand temporal and spatial relationships.

VideoMAE is particularly effective because it learns video representations by predicting missing content, making it robust at understanding actions, movements, and scene changes across multiple frames. The model can identify complex patterns and activities by analyzing how objects and people move and interact throughout the video sequence, providing detailed insights about the video's visual content.

from transformers import VideoMAEFeatureExtractor, VideoMAEForVideoClassification

# Load VideoMAE model and processor
model = VideoMAEForVideoClassification.from_pretrained("facebook/videomae-base")
feature_extractor = VideoMAEFeatureExtractor.from_pretrained("facebook/videomae-base")

# Preprocess frames for analysis
inputs = feature_extractor(frames, return_tensors="pt")
outputs = model(**inputs)
predicted_class = outputs.logits.argmax(dim=-1).item()

print(f"Predicted video action: {predicted_class}")

Code breakdown:

1. Imports and Model Loading:

  • The code imports VideoMAE's feature extractor and classification model from the transformers library
  • It loads the pre-trained "videomae-base" model from Facebook, which is designed to understand and classify video content

2. Model Components:

  • VideoMAEForVideoClassification: The main model that processes video frames
  • VideoMAEFeatureExtractor: Prepares the video frames in a format the model can understand

3. Processing Steps:

  • The feature extractor processes the input frames and converts them to tensors (mathematical representations the model can work with)
  • The model processes these inputs and produces output logits (scores)
  • The highest scoring class is selected using argmax() to determine the predicted action in the video

This model is particularly effective because it can identify complex patterns and activities by analyzing how objects and people move and interact throughout the video sequence. It processes video frames by dividing them into patches and applying self-attention mechanisms to understand temporal and spatial relationships.
