US 2013/0155327 A1 · Method to Process Image Sequences with Sub-Pixel Displacements

Abstract

A method for reducing or removing sub-pixel displacements between images in a sequence of images is disclosed. In the first step, a set of images is acquired using a camera system. In the second step, pairwise distances are computed between every pair of images of the set of images. In the third step, the pairwise distances having the smallest values are identified. In the fourth step, “lucky” image pairs are selected from the image pairs having the smallest displacement. These “lucky” image pairs will have a substantially reduced sub-pixel jitter. In an alternative embodiment, after performing the first step and before performing the second step, the set of images are processed to remove whole pixel displacements between the images in the set of images.

Dependent claims

A method of generating a set of image pairs based on a visual scene, comprising the steps of:

acquiring a plurality of images based on the visual scene;
generating a plurality of measurements based on the plurality of images, wherein each measurement of the plurality of measurements is associated with two images selected from the plurality of images;
selecting a subset of measurements from the plurality of measurements;
and
generating the set of image pairs based on the two images associated with each measurement of the subset of measurements.
