Developers can use lossy compression on images and many other artifacts to reduce size and improve network transfer times. Native program instructions, however, are typically not considered candidates for lossy compression since arbitrary losses in instructions may dramatically affect program output. In this paper we show that lossy compression of compiled native instructions is possible in cer...

An integer reversible implementation of multiple component transform is significant for lossless, unified lossy/lossless and progressive lossy-lossless multi-component or hyper-spectral image coding. In this proposal, we present a reversible integer mapping method for invertible linear transforms. Its effectiveness was evaluated using 2 6-band Landsat TM images and an 80-component hyper-spectra...

This paper develops a theoretical framework for lossy source coding that treats it as a statistical problem, in analogy to the approach to universal lossless coding suggested by Rissanen’s Minimum Description Length (MDL) principle. Two methods for selecting efficient compression algorithms are proposed, based on lossy variants of the Maximum Likelihood and MDL principles. Their theoretical per...

Non-destructive testing and reconstruction of lossy non-uniform transmission lines require solving inverse scattering problems for inhomogeneous one-dimensional (1D) lossy media. Often the source waveform used to probe the medium is unknown, since it cannot be measured separately. This paper shows that the blind deconvolution problem of reconstructing both an unknown source and an unknown lossy...

: Image compression may be lossy or lossless. Lossless compression is preferred for archival purposes and often for medical imaging, technical drawings, clip art, or comics. Lossy compression methods, especially when used at low bit rates, introduce compression artifacts. Lossy methods are especially suitable for natural images such as photographs in applications where minor (sometimes impercep...

The calculation of the local density of states (LDOS) in lossy materials has long been disputed due to the divergence of the homogeneous Green functionwith equal space arguments. For arbitrary-shaped lossy structures, such as those of interest in nanoplasmonics, this problem is particularly challenging. A nondivergent LDOS obtained in numerical methods such as the finite-difference time-domain ...

Absorber is an important component in various optical devices. Here we report a novel type of asymmetric absorber in the visible and near-infrared spectrum which is based on lossy Bragg stacks. The lossy Bragg stacks can achieve near-perfect absorption at one side and high reflection at the other within the narrow bands (several nm) of resonance wavelengths, whereas display almost identical abs...

This paper proposes an effective technique, which can detect malicious manipulations under video lossy compressing data (e.g. H.263) and still-image lossy compressing data (e.g. JPEG). A blockclassification strategy is used to divide DCT-blocks into the flat-blocks and the normal-blocks. Simple features of the both blocks are embedded invisibly. For later authentication, the watermarked frame i...

We consider a novel variant of $d$ -semifaithful lossy coding in which the distortion measure is revealed only to encoder and at run-time, as well an extension it constraint also run-time. Two forms rate redundancy are used analyze pe...
