While we found this technique works well, we note that flash/noflash images do have significant differences due to the change in Our ambient image denoising technique also builds on the bilateral filter. The joint bilateral filter relies on the flash image as an estimator 	./cache/work_7aa2axdawfdf7pwbqly56kdupu.pdf	./txt/work_7aa2axdawfdf7pwbqly56kdupu.txt
