Phase correlation (PC) is a well-established image matching algorithm. It is robust to the variation of image contrast and brightness, but whether it is invariant to local illumination change, particularly sun angle change, is yet to be investigated. This paper presents our study to prove and demonstrate the robustness of illumination invariance of the PC algorithm via mathematical analysis and image...
In this paper, we present a Phase Correlation (PC) based change detection algorithm which is able to automatically detect very small target such as the Mars rover in multi-temporal HiRISE images under illumination variation and camera motion. The robustness of PC to illumination variation was proved by our previous work while the geometric distortion caused by camera motion can be eliminated by PC-based...
