Solves the orthogonal procrutes problem
The orthogonal Procrustes problem is a matrix approximation problem in linear algebra. In its classical form, one is given two matrices $${\displaystyle A}$$ and $${\displaystyle B}$$ and asked to find an orthogonal matrix $${\displaystyle \Omega }$$ which most closely maps See more This problem was originally solved by Peter Schönemann in a 1964 thesis, and shortly after appeared in the journal Psychometrika. This problem is equivalent to finding the nearest orthogonal … See more There are a number of related problems to the classical orthogonal Procrustes problem.

There is an interesting relationship between the subspace distance and their corresponding basis matrices. In particular, by trying to map the basis of $\bm A$ to $\bm B$ using an orthogonal transformation, one can consider the following optimization problem:
Web3.45%. From the lesson. Pose Estimation. In this module we will be learning about feature extraction and pose estimation from two images. We will learn how to find the most salient parts of an image and track them across multiple frames (i.e. in a video sequence). We will then learn how to use features to find the position of the camera with ...
