Wavelet Transforms On The Letter N
John F Schmeelk · 2020
This paper studies the two-dimensional wavelet transform applied to two-dimensional images.The classical technique oftentimes implements the Fourier transform.This paper offers a brief discussion regarding the comparison of the two transforms on a single alphabet, N. It provides a comparison of the global properties present in the Fourier transform technique verses a more localized analysis when the wavelet transform is applied to the same image.The wavelet selected in this study is the derivative of the Gaussian since in some sense offers a nice comparison to the Fourier method.
