The use of lossy compression in medical imaging is controversial, although it is inevitable to reduce large data amounts. In contrast with lossy compression, lossless compression does not impair image quality. In addition to our previous studies, we evaluated virtual 3-dimensional microscopy using JPEG2000 whole slide images of gastric biopsy specimens with or without Helicobacter pylori gastri...

We examine the task of privacy amplification from information-theoretic and coding-theoretic points of view. In the former, we give a one-shot characterization of the optimal rate of privacy amplification against classical adversaries in terms of the optimal type-II error in asymmetric hypothesis testing. The converse bound turns out to be tighter than previous bounds based on smooth min-entrop...

We give a development of the theory of lossy data compression from the point of view of statistics. This is partly motivated by the enormous success of the statistical approach in lossless compression, in particular Rissanen’s celebrated Minimum Description Length (MDL) principle. A precise characterization of the fundamental limits of compression performance is given, for arbitrary data source...

Optical sensing works most efficiently around the singularity of resonances. In pursuit high quality-factor and sensitivity, non-plasmonic nanosensors are desired as metallic materials intrinsically lossy. However, standalone resonant systems dielectric nanoparticles (NPs) generally do not possess a pole or its identification has proven to be hard across complex frequency domain. To solve this ...

In this paper, we present a generalization of the simultaneous diagonalization technique by means of congruence transformations to the general reciprocal lossy multiconductor transmission line case. The method paves the way to solving the inverse problem, i.e., given a lossy multiconductor transmission line system of a given length, recover the transmission line parameters from the impedance or...

We evaluate typical performance of irregular low-density generator-matrix (LDGM) codes, which is defined by sparse matrices with arbitrary irregular bit degree distribution and arbitrary check degree distribution, for lossy compression. We apply the replica method under one-step replica symmetry breaking (1RSB) ansatz to this problem. Typical performance of irregular LDGM codes for lossy compre...

High resolution images acquired by an aerial digital camera and high resolution satellite images are expected to become more powerful data source of GIS. Since the large data volume of a high resolution image brings difficulties in dealing with it, lossy image compression is going to be indispensable. Image quality of a reconstructed image after decompression is usually evaluated by visual insp...

This paper is a revised version of the paper with the same title in the proceedings of ICIP97 (which contains a serious error in g. 1 and in table 1). Abstract This paper presents a lossless block-transform coder based on the Hadamard transform that achieves a compression ratio as good as that of the current lossless JPEG-standard and about 10 to 20% lower than the currently best state-of-the-a...

The throughput degradation of Transport Control Protocol (TCP)/Internet Protocol (IP) networks over lossy links due to the coexistence of congestion losses and link corruption losses is very similar to the degradation of processor performance (i.e., cycle per instruction) due to control hazards in computer design. First, two types of loss events in networks with lossy links are analogous to two...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...
