A Comparative Study of Filter Based Texture Operators Using Mahalanobis Distance
Texture feature extraction operators, which comprise linear filtering, eventually followed by post-processing, are considered. The filters used are Laws' masks, filters deriv...

Costas array generator polynomials in finite fields
—Permutations of order N are generated using polynomials in a Galois field GF(q) where q > N+1, which can be written as a linear transformation on a vector of polynomial coeff...

SURE-LET multichannel image denoising: undecimated wavelet thresholding
We propose an extension of the recently devised SURE-LET grayscale denoising approach for multichannel images. Assuming additive Gaussian white noise, the unknown linear parameter...
