I am reading the paper on 3D reconstruction, ViSER: Video-Specific Surface Embeddings for Articulated 3D Shape Reconstruction, and I encountered the term "canonical space".
What is a "canonical space"? Is it widely used? Is there other use of the term?
In my understanding, a canonical space is a standard, norm space. And we want to convert sample points into that space so that we can perform standard procedures. But I don’t know if that interpretation is correct or not. And I am also interest if it is a common term or very few people use it.
