REMARKS ON KERNEL FOR WAVELET EXPANSIONS IN MULTIDIMENSIONS
Hong-Tae Shim, Joong-Sung Kwon · Journal of applied mathematics & informatics · 2009
In expansion of function by special basis functions, properties of expansion kernel are very important. In the Fourier series, the series are expressed by the convolution with Dirichlet kernel. We investigate some of properties of kernel in wavelet expansions both in one and higher dimensions.
