Claim Text:
1. A computer-implemented method of enhancing one or more images, the method comprising: receiving, by a computer, one or more observed images; identifying, by the computer, a plurality of wavelet bases; estimating, by the computer, a noise variance value; estimating, by the computer, a blurring kernel based on one or more system calibration parameters; determining a low-pass blurring filter operator based on the blurring kernel; determining a downsampling operator; selecting, by the computer, a tuning parameter based on the noise variance value; creating, by the computer, a cost function which generates one or more denoised super-resolution images based on the observed images and the plurality of wavelet bases, the cost function comprising: generating, by the computer, the one or more denoised super-resolution images by minimizing the cost function.
