A novel image registration algorithm based on octa-log-polar Fourier transform (OLPFT) for estimating large translations, rotations, and scalings in images is presented. The OLPFT, which is calculated at points distributed at non-linear increased concentric octagons, approximated log-polar Fourier representations of images accurately. And it can be(More)
The accuracy of the object recognition is the basis for the decision-making subsystem in the centralized-control Mirosot system. This paper proposes a novel cross-power spectrum based approach to detect the orientation of the robots more accurately. In the proposed algorithm, the images of all objects are firstly gotten by image segmentation technologies(More)
