hypergas.hsi2rgb module

Generate RGB image using hyperspectral satellite data.

hypergas.hsi2rgb.Hsi2rgb(wY, HSI, ydim, xdim, d, threshold)[source]

Generate RGB from HSI image data using the HSI2RGB method.

Parameters:

  • wY (numpy.ndarray) – 1D Band wavelengths (nm).

  • HSI (numpy.ndarray) – 2D Radiance matrix (npixels, nbands), e.g., da.stack(z=['y', 'x']).transpose(..., 'bands').

  • ydim (int) – The y dimension size of image.

  • xdim (int) – The x dimension size of image.

  • d (int) – The number (50, 55, 65, or 75) used to determine the illuminant used, if in doubt use d65.

  • thresholdRGB (bool) – True if thesholding should be done to increase contrast.

Returns:

rgb (numpy.ndarray) – dims: (ydim, xdim, 3), where the last dimension corresponds to the color channels (R, G, B).
