Compute an affine transformation matrix from point correspondences

Computes the 2x3 affine transformation matrix that maps src points to dst points. Requires exactly 3 point pairs.

Usage

affine_from_points(src, dst)

Arguments

src

A 3x2 numeric matrix of source points. Column 1 = x, column 2 = y (1-based pixel coordinates).

dst

A 3x2 numeric matrix of destination points. Same convention as src.

Value

A 2x3 numeric matrix.
