OpenGL（或OpenGL ES）中的图像拼接/纹理混合
我有两个 YUV 图像 (YUV 420 SP)，它们已作为纹理加载到片段着色器中。
这些纹理具有重叠区域。
现在，我尝试混合这两种纹理，以便重叠区域的亮度不有任何明显差异。 （基本上缝合图像）

- 你能建议我如何混合/混合/缝合这两个图像的任何方法吗。
- 我在 OpenCV 中遇到了 Alpha Masking 的概念。我不确定它如何适用于 OpenGL。另外，由于我使用的是 YUV 图像，这些图像作为纹理、R 和 RG 组件（用于 Y 和 UV）加载，并在片段着色器中进一步将其转换为 RGB 颜色空间。
注意：我现在不考虑任何几何对齐。我知道混合/缝合后图像看起来不太好，因为图像未正确定向或放置。我的问题只是关于如何处理重叠区域的光度/颜色对齐。
I've got two YUV images (YUV 420 SP), which have been loaded in fragment shader as textures.
These textures are having an overlapping area.
Now, I am trying to blend these two textures such that there should not be any difference visible in the brightness over the overlapping area. (Basically stitching the images)

- Can you suggest any method on how I can mix/blend/stitch these two images.
- I have come across the concept of Alpha Masking in OpenCV. I am not sure how it is applicable in OpenGL. Also, since I am using YUV images, which are loaded as textures, as R and RG component (for Y and UV), and further converting it to RGB Color space in the fragment shader.
Note: I am not considering any geometrical alignment for now. I know after the blending/stitching the image will not quite good looking as the images are not oriented or placed properly. My question is only regarding the photometric/color alignment on how I can handle the overlapping area.
