navigate.model.analysis.camera.compute_signal_to_noise(image, offset_map, variance_map)

Compute the signal-to-noise ratio of an image from offset and variance maps.

Parameters:

• image (np.array) – ZYX image of camera frames.

• offset_map (np.array) – XY image of camera offset in the absence of signal.

• variance_map (np.array) – XY image of camera variance in the absence of signal.

Returns:

snr – XY image of signal-to-noise ratio.

Return type:

np.array
