Right here discover that segments from each movies are returned with a low similarity rating.

Step 9: Performing images-to-video search

You should utilize image-to-video search to retrieve video segments which can be visually much like a given picture. By utilizing TwelveLabs’ picture embedding capabilities and OpenSearch Service’s vector search performance, you possibly can match visible options from a picture with video embeddings within the index. Right here’s the right way to implement this step:

Generate Picture Embeddings

To carry out the search, you first convert the enter picture right into a vector illustration utilizing the TwelveLabs Embed API:

# Create picture embeddings for the enter picture file image_res = twelvelabs_client.embed.create(     model_name="Marengo-retrieval-2.7",     image_file="image-data.jpg",  # Substitute along with your desired picture file ) # Print particulars of the generated embedding print(f"Created picture embedding: model_name={image_res.model_name}") print(f" Mannequin: {image_res.model_name}") # Extract and examine the generated picture embeddings if image_res.image_embedding is just not None and image_res.image_embedding.segments is just not None:     print_segments(image_res.image_embedding.segments) # Retailer the embedding vector for search vector_search = image_res.image_embedding.segments[0].embeddings_float print("Generated Picture Embedding Vector:", vector_search) 

Key factors:

• The Marengo-retrieval-2.7 mannequin is used to generate a dense vector embedding for the enter picture.
• The embedding captures visible options resembling shapes, colours, and patterns, enabling efficient matching with video embeddings

Carry out vector search in OpenSearch

After the picture embedding is generated, you utilize it as a question vector to carry out a k-nearest neighbor (kNN) search in OpenSearch:

# Carry out vector search query_vector = vector_search image_to_video_search = search_similar_segments(query_vector) # print(text_video_search)      print_search_results(image_to_video_search)
