stacker.combine_frames

combine_frames(frames_A, frames_B)

Combines two 2D numpy arrays (frames_A and frames_B) into a single array.

This function takes two 2D numpy arrays of the same shape and combines them into a new array. The upper triangular part (excluding the diagonal) of the resulting array is filled with the corresponding elements from frames_A, while the lower triangular part (including the diagonal) is filled with the corresponding elements from frames_B.

Parameters:

frames_Anumpy.ndarray

A 2D numpy array.

frames_Bnumpy.ndarray

A 2D numpy array of the same shape as frames_A.

Returns:

numpy.ndarray

A new 2D numpy array with combined elements from frames_A and frames_B.

Examples

>>> import stacker as st
>>> import numpy as np
>>> frames_A = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
>>> frames_B = np.array([[9, 8, 7], [6, 5, 4], [3, 2, 1]])
>>> st.combine_frames(frames_A, frames_B)
array([[9., 2., 3.],
       [6., 5., 6.],

[3., 2., 1.]])
