Lossless Prioritized Embeddings [PDF]
SIAM Journal on Discrete Mathematics, 2020 Given metric spaces $(X,d)$ and $(Y,ρ)$ and an ordering $x_1,x_2,\ldots,x_n$ of $(X,d)$, an embedding $f: X \rightarrow Y$ is said to have a prioritized distortion $α(\cdot)$, if for any pair $x_j,x'$ of distinct points in $X$, the distortion provided by $f$ for this pair is at most $α(j)$.

Lossless Analog Compression [PDF]
IEEE Transactions on Information Theory, 2019 We establish the fundamental limits of lossless analog compression by considering the recovery of arbitrary m-dimensional real random vectors x from the noiseless linear measurements y=Ax with n x m measurement matrix A. Our theory is inspired by the groundbreaking work of Wu and Verdu (2010) on almost lossless analog compression, but applies to the ...

Multiseed Lossless Filtration [PDF]
IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2004 We study a method of seed-based lossless filtration for approximate string matching and related bioinformatics applications. The method is based on a simultaneous use of several spaced seeds rather than a single seed as studied by Burkhardt and Kärkkäinen [1].

Practical Secret Image Sharing Based on the Chinese Remainder Theorem
Mathematics, 2022 Compared with Shamir’s original secret image sharing (SIS), the Chinese-remainder-theorem-based SIS (CRTSIS) generally has the advantages of a lower computation complexity, lossless recovery and no auxiliary encryption. However, general CRTSIS is neither

Progressive Secret Sharing with Adaptive Priority and Perfect Reconstruction
Journal of Imaging, 2021 A new technique for progressive visual secret sharing (PVSS) with adaptive priority weight is proposed in this paper. This approach employs the bitwise and eXclusive-OR (XOR) based approaches for generating a set of shared images from a single secret ...
