Rotation Measurements using Rotation Invariant Phase Only Correlation

Abstract

Rotation Invariant Phase Only Correlation (RIPOC) is one of the applications of Phase Only Correlation (POC). RIPOC can correlate two images even though there is rotation between two images. It is also able to measure the rotation angle between two images. Like POC, RIPOC processes images macroscopically so it can correlate the images of which characteristic points are difficult to be extracted. We present the experimental results of the ability to detect the rotation angle by RIPOC.
