pixel_level_peak_finder_2d

giant.image_processing.peak_finders:

giant.image_processing.peak_finders.pixel_level_peak_finder_2d(surface, blur=True)

This function returns a numpy array containing the (x, y) location of the maximum surface value to pixel level accuracy.

Optionally, a blur can be applied to the surface before locating the peak to attempt to remove high frequency noise.

Parameters:

• surface (Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]) – A surface, or image, to use

• blur (bool) – A flag to indicate whether to apply Gaussian blur to image

Returns:

The (x, y) location of the maximum surface values to pixel level accuracy.

Raises:

ValueError – If the provided surface is not 2 dimensional

Return type:

ndarray[tuple[Any, …], dtype[integer]]
