Pauli decomposition via the fast Walsh-Hadamard transform [PDF]
New Journal of PhysicsThe decomposition of a square matrix into a sum of Pauli strings is a classical pre-processing step required to realize many quantum algorithms. Such a decomposition requires significant computational resources for large matrices. We present an exact and

Low computational complexity variable block size (VBS) partitioning for motion estimation using the Walsh Hadamard transform (WHT) [PDF]
, 2009 Variable Block Size (VBS) based motion estimation has been adapted in state of the art video coding, such as H.264/AVC, VC-1. However, a low complexity H.264/AVC encoder cannot take advantage of VBS due to its power consumption requirements.

Complexity adaptation in H.264/AVC video coder for static cameras [PDF]
, 2009 H.264/AVC uses variable block size motion estimation (VBSME) to improve coding gain. However, its complexity is significant and fixed regardless of the required quality or of the scene characteristics. In this paper, we propose an adaptive complexity
