我在matlab中尝试缝合图像,但得到难看的重叠线条.如何正确混合图像？目前我正在使用下面的代码,但它混合得太多(特别是建筑物窗户与幽灵文物混合,黑色建筑物也是如此).

%Tx - how much to move picture by x, Ty - by y (homography)
cropX = size(imcyl2, 2); %second image x size
xdimfirst = size(imcyl1, 2); %first image x size
ydimfirst = size(imcyl1, 1); %first image y size
xoverlap = xdimfirst - Tx;
newImg = imcyl1;
for y = 1:size(imcyl2, 1)
   for x = 1:cropX
       if ((Tx+x) > 0 && (Ty+y) >0)
       % if we are in the overlap region, then we need to blend.
               scale1 = (xoverlap - …

我不想为app标签创建任何自定义布局,只想将其颜色更改为白色(现在为黑色).我怎么能这样做？
