Apparatus for enhancing images using flow estimation
First Claim
Patent Images
1. Apparatus for enhancing an image comprising:
- a first imaging device for producing images at a first resolution;
a second imaging device for producing images at a second resolution; and
an image processor for aligning said images from said first and second imaging devices to form a plurality of aligned images, computing a flow estimation for each of the aligned images, and using the flow estimations to enhance regions in a first aligned image with information from at least one other aligned image.

Abstract
A method and apparatus for accurately computing parallax information as captured by imagery of a scene. The method computes the parallax information of each point in an image by computing the parallax within windows that are offset with respect to the point for which the parallax is being computed. Additionally, parallax computations are performed over multiple frames of imagery to ensure accuracy of the parallax computation and to facilitate correction of occluded imagery.
