Box Spline Wavelet Frames for Image Edge Analysis [PDF]
, 2013 We present a new box spline wavelet frame and apply it for image edge analysis. The wavelet frame is constructed using a box spline of eight directions. It is tight and has seldom been used for applications.

Disjoint sparsity for signal separation and applications to hybrid inverse problems in medical imaging [PDF]
, 2017 The main focus of this work is the reconstruction of the signals f and gi, i=1,\u2026,N, from the knowledge of their sums hi=f+gi, under the assumption that f and the gi's can be sparsely represented with respect to two different dictionaries Af and Ag ...

Diffusion-inspired shrinkage functions and stability results for wavelet denoising [PDF]
, 2003 We study the connections between discrete 1-D schemes for non-linear diffusion and shift-invariant Haar wavelet shrinkage. We show that one step of a (stabilised) explicit discretisation of nonlinear diffusion can be expressed in terms of wavelet ...

Color image encryption and decryption using Hill Cipher associated with Arnold transform [PDF]
, 2016 Image security over open network transmission is a big concern nowadays. This paper proposes another methodology for color image encoding and decoding using two stage Hill Cipher method which is connected with Arnold Transformation.

Grayscale-image encryption using Random Hill Cipher over SLn(F) associated with Discrete Wavelet Transformation [PDF]
, 2013 Image data are highly sensitive and prone to incidental decoding by intruders. The security of image data in an insecure network is therefore a major issue.

Construction of Energy Preserving QMF [PDF]
, 2016 Recently, a family of perfect reconstruction (PR) quadrature mirror filterbanks (QMF) with finite impulse response filters (FIR) from systems of biorthogonal refinable functions and wavelets were introduced and also applied to image processing.
