Abstract: Systems and methods for registering hemispheric images obtained using a fisheye lens for panoramic viewing, relating to spatial alignment and color balancing of complement half-side images derived from the hemispheric images. The systems and methods for spatial alignment determine the displacement of the digitized recorded images using a single translation and rotation model of distortion, which further evaluates the center of projection, and the extent of translation and rotation. The system and method for color balancing iteratively increase (or decrease) the values of pixels near the edge (discontinuity) between the two half-sides of an image, each time taking into consideration the average difference of pixel color across a smaller strip of the edge near the pixel. This invention removes the color differential but does not remove any detail underlying the features of the image.
