I'm looking at this link: HaarWaveletTransform. Given an array of N sample points, it subdivides the array into two arrays of size N/2: Array1: Averages adjacent sample points. Array2: Computes a finite difference between sample points. You can then apply recursively k many times. In the end...

Yes, but there is a trick using augmented/homogeneous coordinates where if you write points (x, y, z, 1) and use 4x4 matrix, you can represent the translation and linear transformation (I want to restrict to rotation, however), as a single matrix. See "Augmented Matrix" from...

Background: I have a set of known 3D feature points {x_i} on the surface of an object in some reference position/orientation at time t = 0. At t > 0 the object will have moved by a rigid transform. I am using computer vision to estimate the position of the 3D feature points {y_i}. I want to...
