+    A Semantic Search Engine that understands the Content & Context of your Queries. 
+    <br>
+    Use Multi-Modal inputs like Text-Image or a Reverse Image Search to search a Vector Database of over 15k Images. <a href="https://huggingface.co/spaces/Snehil-Shah/Multimodal-Image-Search-Engine">Try it Out!</a>

+<h3>• About The Project</h3>
+
+At its core, the Search Engine is built upon the concept of **Vector Similarity Search**.
+All the Images are encoded into vector embeddings based on their semantic meaning using a Transformer Model, which are then stored in a vector space.
+When searched with a query, it returns the nearest neighbors to the input query which are the relevant search results.
+
+<p align="center"><img src="./assets/encoding_flow.png"></p>
+
+We use the Contrastive Language-Image Pre-Training (CLIP) Model by OpenAI which is a Pre-trained Multi-Modal Vision Transformer that can semantically encode Words, Sentences & Images into a 512 Dimensional Vector. This Vector encapsulates the meaning & context of the entity into a *Mathematically Measurable* format.

+
+The Images are stored as vector embeddings in a Qdrant Collection which is a Vector Database. The Search Term is encoded and run as a query to Qdrant, which returns the Nearest Neighbors based on their Cosine-Similarity to the Search Query.

+
+**The Dataset**: All images are sourced from the [Open Images Dataset](https://github.com/cvdfoundation/open-images-dataset) by Common Visual Data Foundation.
