如何在OpenCV C ++中合并（缝合）2个没有黑点的图像

Question

I have 2 images and when I stitch them, there'll be some black area in the resulting image. I'll share the images. so how can I stitch them without the black area?

I have a homography matrix and I stitch them using ROI.

But I have a search about "seamless clone" in OpenCV, but I don't yet know it'll help me. I need advice.

I want like that: enter image description here

If you dont need a blending:

pseudo code:

inputs: image A, image B, backgroundColorRange X
outputs: image O

for each pixel in the output image:
    if(pixel(A) == X AND pixel(B) == X) pixel(O) = X;
    else if (pixel(A != X) AND pixel(B == X) pixel(O) = pixel(A);
    else if (pixel(A == X) AND pixel(B == X) pixel(O) = pixel(B);
    else if (pixel(A != X) AND pixel(B != X) pixel(O) = 0.5*pixel(A) + 0.5*pixel(B)
