Block matching threshold for the first step of BM3D (hard thresholding), i.e. maximum distance for which two blocks are considered similar. Value expressed in euclidean distance.

Block matching threshold for the second step of BM3D (Wiener filtering), i.e. maximum distance for which two blocks are considered similar. Value expressed in euclidean distance.
groupSize
Maximum size of the 3D group for collaborative filtering.
slidingStep
Sliding step to process every next reference block.
beta
Kaiser window parameter that affects the sidelobe attenuation of the transform of the window. Kaiser window is used in order to reduce border effects. To prevent usage of the window, set beta to zero.
normType
Norm used to calculate distance between blocks. L2 is slower than L1 but yields more accurate results.
step
Step of BM3D to be executed. Possible variants are: step 1, step 2, both steps. Currently only Haar transform is supported.
