HSTI 0.0.3

The NEWTEC HSTI package contains fundamental functions for the data analysis of hyperspectral thermal images (HSTI).

This package contains functions used in data processing of hyperspectral images captured using a scanning Fabry-Pérot interferometer (FPI). This includes transmission simulations of the FPI itself.

Package Documentation and Modules:

Image analysis

hsti_import

'import_data_cube(path)'

This function imports the hyperspectral thermal datacube from the raw output of the camera. The path that the function uses as input must be the one containing the 'images' directory.

hsti_export

'export_data_cube(data_cube, folder_name)'

This function takes an HSTI numpy array and exports it as individual .ppm images to a folder given by folder_name.

remove_bad_px

'remove_stuck_px(cube)'

'remove_outlying_px(cube, cut_off)'

remove_vignetting

'remove_vignette()'

the function takes a single HSTI as input and returns a new vignetting corrected cube.

spectral_debending

'debend(cube, central_mirror_sep)'

the function takes a single HSTI as input and returns a new spectral bending corrected cube.

fill_gaps

farthest_point_sampling

'fps(points, n_seeds)'

Function which distributes n_seeds (a numper of points) equally within a lists of points to obtain furthest point sampling.

The function takes in a list of points. Every entry in the list contains both the x and y coordinate of a given point. It returns the coordinates of the selected sample points

voronoi_partitioning

mse

'mse(lst1, lst2)'

the function returns the mean square error (MSE) between two lists of same length.
