Fast Algorithm for Walsh Hadamard Transform on Sliding Windows

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010
This paper proposes a fast algorithm for Walsh Hadamard Transform on sliding windows which can be used to implement pattern matching most efficiently. The computational requirement of the proposed algorithm is about 1.5 additions per projection vector per sample, which is the lowest among existing fast algorithms for Walsh Hadamard Transform on sliding

Unified Matrix Treatment of the Fast Walsh-Hadamard Transform

IEEE Transactions on Computers, 1976
A unified matrix treatment is presented for the various orderings of the Walsh-Hadamard (WH) functions using a general framework. This approach clarifies the different definitions of the WH matrix, the various fast algorithms and the reorderings of the WH functions.

Recursive Algorithm for Sliding Walsh Hadamard Transform

IEEE Transactions on Signal Processing, 2014
In this paper, a recursive sliding transform (RST) algorithm is proposed for the fast implementation of the Walsh Hadamard Transform (WHT) on sliding windows. The proposed RST algorithm accelerates the sliding WHT process by recursively reducing the order of WHT.

Real-Time Walsh-Hadamard Transformation

IEEE Transactions on Computers, 1972
A technique for obtaining the digital Walsh-Hadamard transform of two-dimensional discrete pictures in real time is presented. A considerable reduction in total time for the transformation of a picture results since the process of scanning and digitizing one picture line overlaps with computations on the previous line. This is accomplished by operating
