VBM3D only applies to grayscale images; we convert our input images to gray scale and apply both our method and VBM3D on them. (We saved VBM3D results in 16-bit format before topmapping for fair comparison.) Our approach works noticeably better because we use a global flow algorithm which registers images more accurately than the block matching technique used by VBM3D. No ground truth is captured for this scene because of dynamic flames.
