Wavelet packets and co-occurrence matrices for texture-based image segmentation
In this paper, a texture-based segmentation approach using wavelet packets, co-occurrence matrices and normalised modified histogram thresholding is discussed and developed. Back...

Block Based Deconvolution Algorithm Using Spline Wavelet Packets
This paper proposes robust algorithms to deconvolve discrete noised signals and images. The solutions are derived as linear combinations of spline wavelet packets that minimize so...
