Fuzzy quantization based bit transform for low bit-resolution motion estimation

作者：

Highlights：

• This study addresses a bit transform for low bit-resolution motion estimation.

• We formulate the bit-resolution reduction into optimum quantization.

• The membership function eliminates the mismatch of hard thresholding due to noises.

• SAD is a fast matching metric suitable for low bit-depth motion estimation.
