A contrast-enhanced image can be converted back to the original image, as the transformation applied is linear. Contrast stretching maps one intensity range present in the image to another intensity range.

NettetThe tomography projection operation is a linear transformation. In addition to the data-fidelity term corresponding to a linear regression, we penalize the L1 norm of the image to account for its sparsity. The resulting optimization problem is called the Lasso. We use the class Lasso, that uses the coordinate descent algorithm.
