Inventor: CHEN GUANGYI
IPC: G06T3/00
Filed: 2012-12-24
Abstract: An image registration method is disclosed for processing a distorted image into a registered image that is aligned with reference to an original image. Distortions from the original image may include scaling, rotation, and noise. The method is based on correlating Radon transforms of both images to determine the rotation angle, and the scaling factor is determined by dividing averages of the overall luminance of each image on the assumption that any added noise will cancel. The Fast Fourier Transform (FFT) is used to estimate global spatial shifts. In one embodiment, the distorted image is first scaled to the size of the original image before being rotated. In another embodiment, the original image is first scaled to the size of the distorted image before rotating the distorted image, and finally scaling it to match the original image. A corresponding system for image registration is also provided.

The rotor pole pieces (107) include a series of evenly-spaced slots (109) and a central void (108). The slots (109) are of various lengths to direct the flux from the magnets (103) into the air gap (121) at a desired angle normal to the rotor surface. The slots 109 may be varied in width and angle to achieve the desired lowest waveform distortion under load and the highest air gap flux. The slots (109) also contribute to changing the saliency of the rotor.
