Parallel Scales for More Accurate Displacement Estimation in Phase-Based Image Registration

Phase-based methods are commonly applied in image registration. When working with phase-difference methods only a single scale is employed, although the algorithms are normally iterated over multiple scales, whereas phasecongruency methods utilize the the phase from multiple scales simultaneously. This paper presents an extension to phasedifference methods employing parallel scales to achieve more accurate displacements. Results are also presented clearly favouring the use of parallel scales over single scale in more than 95% of the 120 tested cases.
