Measurement operators, static and dynamic.

There are six classes contained in this module, each representing a different type of measurement operator. Three of them are static, i.e. they are used to simulate measurements of still images, and three are dynamic, i.e. they are used to simulate measurements of moving objects, represented as a sequence of images.

The inheritance tree is as follows:

  Linear          DynamicLinear
    |                   |
    V                   V
LinearSplit     DynamicLinearSplit
    |                   |
    V                   V
HadamSplit      DynamicHadamSplit

Classes

DynamicLinear(H, time_dim[, meas_shape, ...])	Simulates the measurement of a moving object \(y = H \cdot x(t)\).
FreeformLinear(H[, meas_shape, meas_dims, ...])	Simulate linear measurements in a region of interest
FreeformLinearSplit(H[, meas_shape, ...])	Simulate split measurements in a region of interest
HadamSplit2d(h[, M, order, fast, ...])	Simulate 2D Hadamard split acquisitions.
Linear(H[, meas_shape, meas_dims, ...])	Simulates linear measurements
LinearSplit(H[, meas_shape, meas_dims, ...])	Simulate linear measurements by splitting an acquisition matrix \(H\in \mathbb{R}^{M\times N}\) that contains negative values.
