Word Embedding for Computer Vision

Technical Discussions
#1

Embedding is method of converting the word into numeric value with meaning associated with it. Is embedding in computer vison means converting photos with numeric value ? if yes

  • How different is pixel value from embedding, since pixel value is also numeric?

If you take the two photos of one person - p11, p12 and one from a different person p21 and calculate the corresponding embedding say: ep11, ep12 and ep21.

Then, the embedding of the same person will be nearby. This is how you visualize it in 2d space (though it is going to be around 128-dimensional space).

Pixels comparison would not yield anything while by comparing embeddings you can identify people.

Thanks for your answer. I understand now
