‌Average Pixel

Here, the final pixel is the weighted average of all the candidate pixels. An alpha channel is produced: 1.0 where texture is present, and 0.0 in the empty areas of the texture map that aren’t used or weren’t visible in the source imagery. If an alpha channel is present in the source images, it is included in the weighted averaging process and output alpha values can range between 0 and 1.

Use the Average Pixel method with accurate meshes and good tracking, to produce a final texture with low noise—lower than the noise in the source images. You will want to add noise back in to final renders that use this texture so that it does not look too smooth.

If the tracking and meshing don't match very well, the produced texture will be very blurry. (See Best Pixel below.)
