shoot.num.find_signed_peaks_2d

shoot.num.find_signed_peaks_2d(data, wx, wy, paral=False)

Find local extrema (minima and maxima) in 2D field

Parameters:

• data (ndarray) – 2D data array to search for peaks.

• wx (int) – Window width in x direction for local extrema detection.

• wy (int) – Window width in y direction for local extrema detection.

• paral (bool, default False) – Use parallel implementation if True, serial if False.

Returns:

• minima (ndarray) – Array of (i, j) indices for local minima.

• maxima (ndarray) – Array of (i, j) indices for local maxima.
