Web• Jensen-Shannon divergence: f(x) = xlog 2x x+1 + log 2 x+1, JS(P;Q) = D P P+ Q 2 + D Q P+ Q 2 : Moreover, p JS(PkQ) is a metric on the space of probability distributions [ES03]. Remark 7.3. If D f(PkQ) is an f-divergence, then it is easy to verify that D f( P+ Q kQ) and D f(Pk P+ Q ) are f-divergences for all 2[0;1]. In particular, D f(QkP ... WebIn this paper, based on a discrete total variation model, a modified discretization of total variation (TV) is introduced for image processing problems. Two optimization problems corresponding to compressed sensing magnetic resonance imaging (MRI) data reconstruction problem and image denoising are proposed. In the proposed method, …

Webto the total variation distance1 V(P;Q) = P n i=1 jp i q ijby a generalization of Pinsker’s inequality: 2 V2(P;Q) D (PkQ) for 2(0;1]. (8) (See Theorem 31 below.) For = 1 this is the normal version of Pinsker’s inequality, which bounds total variation distance in terms of the square root of the Kullback-Leibler divergence. C.

Then, we define the total variation of an image as the ℓ 1 norm of its gradient field amplitude. This new definition of the total variation yields sharp edges and has better isotropy ... toys baby sitting up
