Abstract
A method for converting a rectilinear image and a focal length into a cylindrical image parameterized by a height of the cylinder and an angular distance in a single buffer on a remote processing device. The method, on the remote processing device, comprising joining two or more images together to form a panoramic image with corrected perspective. The rectilinear transformation is “in-place” and requires only one buffer. Color correction and motion estimation is also carried out on the remote device. In an alternate embodiment, a computer readable medium corresponding to the above method is described.
