are these highly exposed regions in the source images?

Yes, but there are many pictures from different angles corresponding to the same place on the model, some pictures are high exposure, some are not.
thank you for your reply,
good suggestion, a different blending procedure might be better, pls try
I did an experiment. Set the color of the border of the texture block to black as the boundary condition of the Poisson calculation, and the texture map result is shown in the figure. Does this mean that there is a problem with setting the edge color of the texture block in LocalSeamLeveling, causing the Poisson calculation to be wrong.
I'm not sure if my guess is correct.
Interesting experiment. However not clear to me what is the results before and after, and which edge did you set to black exactly. Can you add more screenshots?

I set the junction of different textures to black, and the original code is set to the average color. By comparison, I suspect that openmvs misses some border pixels, doesn't change their color, causing the poisson calculation to still use the original color, which leads to weird transition areas between different textures.
This is the mask image I saved, and you can see that some edges are not set to gray "border".
In the DrawLine function, "Bresenham's line algorithm" is used to calculate the texture edge pixels. Is there any problem here? Looking forward to your reply.
thanks for the detailed experiment a couple of thoughts:
most probably though might be a problem with drawing the line, like you say, or something related; it would be of great help if you could look into this and fix it; you could compare on how this is done in mvs-texturing
Hi, for texture maps there are many area luminosity highly exposed. Is there a suitable way to reduce this phenomenon? Or is there any way to lower the weight of this region, giving priority to non-highly exposed image regions. Looking forward to your reply.![111](https://github.com/cdcseacave/openMVS/assets/56535633/158714c0-ef14-4080-a000-6e9e87415190)
