Whereas this may seem easy for a human being, it remains a challenging and ambiguous problem for computer-based techniques. This is especially true when the sen

This can be expressed as. where . is the measurement matrix, . contains products of the shape coefficients with the motion parameters, and . contains the shape basis.

As a consequence, constraintsmust be incorporated into the factorization to overcome these issues.
