Adaptive image acquisition for multiframe reconstruction

摘要

Multiframe reconstruction combines a set of acquired images into a reconstructed image. Here, which images to acquire are selected based at least in part on the content of previously acquired images. In one approach, a set of at least three images of an object are acquired at different acquisition settings. For at least one of the images in the set, the acquisition setting for the image is determined based at least in part on the content of previously acquired images. Multiframe image reconstruction is applied to the set of acquired images to synthesize a reconstructed image of the object.

主权项

1. A method for multiframe reconstruction of an object comprising:
acquiring a set of K images of the object at different acquisition settings, where K≧2; for a (k+1)st of the K acquired images, where k≧1, after acquiring the first k images, determining the acquisition setting for the (k+1)st image based at least in part on selecting the acquisition setting to optimize a cost function, wherein one component of the cost function is based on an error between (a) an estimated image ŝk+1 that is a multiframe reconstruction of the object from the (k+1) acquired images and (b) an ideal image; and applying multiframe reconstruction to the set of K images, wherein the multiframe reconstruction estimates the image ŝK from the K acquired images based on minimizing the error between the estimated image ŝK and the ideal image.
