Description

We address the problem of constructing one higher-resolution image from several observed frames of the same resolution.The relative warping between images is supposed to be a translation. Techniques for super resolution are described.

The main reconstruction procedure is based on ridge regression (Tikhonov regularization). The processing is partially performed in the frequency domain and heavily uses the Fourier transform.
