You can average the vectors from all sampled frames (Global Average Pooling) to create one unique "fingerprint" for the entire file. 5. Implementation (Python Snippet)
The frames must be formatted to match the model’s requirements: Usually to
Use a 3D CNN like I3D or VideoMAE which processes temporal data. 3. Pre-process the Data Download: video5179512026745012956.mp4 (5.75 MB)
Depending on what you want the "feature" to represent, choose a model:
Convert the images into numerical arrays (tensors). 4. Extract the Global Feature Vector You can average the vectors from all sampled
Instead of the final classification layer (which would say "dog" or "running"), you extract the output from the (often called the "bottleneck" or "pooling layer").
Use ResNet-50 or ViT (Vision Transformer) pre-trained on ImageNet. Extract the Global Feature Vector Instead of the
Subtract the mean and divide by the standard deviation (specific to the dataset the model was trained on).
