Functions

angle_from_disp(disp, mirror_grid_dist)

detect_phase(img, grid_pitch[, window, boundary])

Detect the phase modulation along the coordinate axes by convolution with a gaussian window or a triangular window, see [1] for more details.

disp_fields_from_phases(phase_x, phase_x_0, ...)

Determine the displacements of every pixel based on the phase modulation along two axes in two configurations, see [1] for more details.

disp_from_grids(grid_undeformed, ...[, ...])

Determine the displacements of every pixel based the image of an undeformed grid and a deformed grid.

disp_from_phases_single_component(phase, ...)

Determine the displacement of every pixel based on the phase modulation in two configurations, see [1] for more details.
