DOI: 10.1107/s1600577520013326
Abstract: Increases in X-ray brightness from synchrotron light sources lead to a requirement for higher frame rates from hybrid pixel array detectors (HPADs), while also favoring charge integration over photon counting. However, transfer of the full… read more here.

DOI: 10.1109/access.2019.2963170
Abstract: Although there exist many researches on the compression of original non-encrypted binary images, few approaches focus on the compression of encrypted binary images. As binary images like contract, signature, halftone images are still used widely… read more here.

DOI: 10.1109/tit.2023.3247601
Abstract: We consider a novel variant of $d$ -semifaithful lossy coding in which the distortion measure is revealed only to the encoder and only at run-time, as well as an extension of it in which the… read more here.

DOI: 10.1109/tpds.2022.3194695
Abstract: Vast volumes of data are produced by today's scientific simulations and advanced instruments. These data cannot be stored and transferred efficiently because of limited I/O bandwidth, network speed, and storage capacity. Error-bounded lossy compression can… read more here.

DOI: 10.1121/1.4988758
Abstract: Despite its temporal precision, the auditory system does not encode fine detail of some classes of natural sounds. For example, sounds known as “auditory textures” seem to be encoded and retained with a lossy, compressed… read more here.

DOI: 10.3390/e21060580
Abstract: We established a universality of logarithmic loss over a finite alphabet as a distortion criterion in fixed-length lossy compression. For any fixed-length lossy-compression problem under an arbitrary distortion criterion, we show that there is an… read more here.
