Total Variation based CS reconstruction It has been suggested that this section be split out into another article titled Total variation reconstruction. Discuss May Motivation and Applications Role of TV regularization Total variation can be seen as a non-negative real -valued functional defined on the space of real-valued functions for the case of functions of one variable or on the space of integrable functions for the case of functions of several variables.
For signals, especially, total variation refers to the integral of the absolute gradient of the signal. In signal and image reconstruction, it is applied as total variation regularization where the underlying principle is that signals with excessive details have high total variation and that removing these details, while retaining important information such as edges, would reduce the total variation of the signal and make the signal subject closer to the original signal in the problem.

Other approaches also include the least-squares as has been discussed before in this article. These methods are extremely slow and return a not-so-perfect reconstruction of the signal.
The current CS Regularization models attempt to address this problem by incorporating sparsity priors of the original image, one of which is the total variation TV. Conventional TV approaches are designed to give piece-wise constant solutions.
Some of these include as discussed ahead - constrained l1-minimization which uses an iterative scheme.
This method, though fast, subsequently leads to over-smoothing of edges resulting in blurred image edges. This has been used in computed tomography CT reconstruction as a method known as edge-preserving total variation.
Recent progress on this problem involves using an iteratively directional TV refinement for CS reconstruction. In the second stage, the CS reconstruction model is presented by utilizing directional TV regularizer.
More details about these TV-based approaches - iteratively reweighted l1 minimization, edge-preserving TV and iterative model using directional orientation field and TV- are provided below.Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).
There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy.
