fit_transform

Problem

Given a corresponding sets of 2D points A and B, find and apply an optimal transformation matrix to bring set A as close as possible to set B.

Solution

• fit_transform implements full Kabsch algorithm for datasets where N >= 3
• closeness of sets is understood as RMSD
• this implementation focuses on 2D points only, but can be easily generalised to support more dimensions

API

• fitTransform(A, B) -> A' -- returns a transformed dataset
• kabsch(A, B) -> C -- returns an optimal rotation matrix

Installation

npm install fit_transform
