What is Non-local image reconstruction for efficient BTF synthesis about?

Figure : A couch textured with a repeating BTF pattern, illustrating BTF synthesis results. From left to right: Our method using 1 sample per pixel (spp) and non-local image reconstruction for BTF generation; unbiased Monte Carlo reference with 128 spp; unbiased Monte Carlo path tracing result with 1 spp. Synthesizing the BTFs took 8 minutes, 320 minutes and 7 minutes respectively. Please note that the remaining variance in our BTF, when comparing to the reference, reduces to an imperceptible level with 4 spp.
