MATLAB: 2-Band Blending on the following stitching

Question

Let us say I got two images and stitch them together. Now, how could we use a 2-Band Blending on this? Or other simple blending approach, I got limited time. Any help would be appreciated.

What I am using now is straight forward and not consider a Blending Approach:

merge_output = output1 .* 0.5 + output2 .* 0.5;
figure, imshow( merge_output, 'XData', xdata , 'YData', ydata ), axis on, impixelinfo;

Answer 1

The simplified solution I found:

1. Merge
2. Separate high and low frequency channels
3. Smooth them respectively
