A computer method of creating a super-resolved grayscale image from
lower-resolution images using an L.sub.1 norm data fidelity penalty term
to enforce similarities between low and a high-resolution image estimates
is provided. A spatial penalty term encourages sharp edges in the
high-resolution image, the data fidelity penalty term is applied to space
invariant point spread function, translational, affine, projective and
dense motion models including fusing the lower-resolution images, to
estimate a blurred higher-resolution image and then a deblurred image.
The data fidelity penalty term uses the L.sub.1 norm in a likelihood
fidelity term for motion estimation errors. The spatial penalty term uses
bilateral-TV regularization with an image having horizontal and vertical
pixel-shift terms, and a scalar weight between 0 and 1. The penalty terms
create an overall cost function having steepest descent optimization
applied for minimization. Direct image operator effects replace matrices
for speed and efficiency.
