Motion estimation for panoramic digital camera |
摘要 |
A method for estimating the motion between a first image and a second image in a system for creating a panoramic image from a plurality of images taken by a camera, the method comprising the steps of: downsampling a first image in a first direction and in a second direction; downsampling a second image in a first direction and in a second direction; filtering the first and the second image so as to filter out any global illumination changes between the first image and the second image; calculating a first displacement along the first direction between the first downsampled image along the first direction and the second downsampled image along the first direction; and calculating a second displacement along the second direction between the first downsampled image along the second direction and the second downsampled image along the second direction. In an alternate embodiment, a device and computer readable medium corresponding to the above method is described.
