What is the difference between Walsh and Hadamard transform?
In the generalized form Walsh transform and the Walsh Hadamard transform are different so far as the kernel composition is concerned as they are ordered differently.
The generalized Walsh kernel is asymmetric, whereas the generalized Hadamard kernel is symmetric.
What is the Walsh transform in image processing?
The Walsh-Hadamard transform is used in a number of applications, such as image processing, speech processing, filtering, and power spectrum analysis.
It is very useful for reducing bandwidth storage requirements and spread-spectrum analysis.
What is the formula for the Walsh transform?
MacWilliams and Sloane [287, Theorem 5, p. 422] give a description of the fast Walsh transform.
H n = M n ( 1 ) M n ( 2 ) ⋯ M n ( n ) , where M n ( i ) = I 2 n − i ⊗ H 1 ⊗ I 2 i − 1 , and I m is the m × m identity matrix.
y = fwht( x , n ) returns the n -point discrete Walsh-Hadamard transform. y = fwht( x , n , ordering ) specifies the ordering to use for the returned Walsh-Hadamard transform coefficients.
