Deep Reformulated Laplacian Tone Mapping [PDF]
arXiv, 2021 Wide dynamic range (WDR) images contain more scene details and contrast when compared to common images. However, it requires tone mapping to process the pixel values in order to display properly. The details of WDR images can diminish during the tone mapping process.

Phase-based Ranging in Narrowband Systems with Missing/Interfered Tones [PDF]
arXiv, 2022 The growth in the number of low-cost narrow band radios such as Bluetooth low energy (BLE) enabled applications such as asset tracking, human behavior monitoring, and keyless entry. The accurate range estimation is a must in such applications. Phase-based ranging has recently gained momentum due to its high accuracy in multipath environment compared to

Two-tone spectroscopy of a SQUID metamaterial in the nonlinear regime [PDF]
Phys. Rev. Research 1, 033096 (2019), 2019 Compact microwave resonantors made of superconducting rings containing Josephson junctions (SQUIDs) are attractive candidates for building frequency tunable metamaterials with low losses and pronounced nonlinear properties. We explore the nonlinearity of a SQUID metamaterial by performing a two-tone resonant spectroscopy.

Proceedings of the National Academy of Sciences of the United States of America, 2014 Significance Experimental animals are usually raised in small, so-called standard cages, depriving them of numerous natural stimuli. We show that raising mice in an enriched environment, allowing enhanced physical, social, and cognitive stimulation ...

Unsupervised HDR Image and Video Tone Mapping via Contrastive Learning [PDF]
arXiv, 2023 Capturing high dynamic range (HDR) images (videos) is attractive because it can reveal the details in both dark and bright regions. Since the mainstream screens only support low dynamic range (LDR) content, tone mapping algorithm is required to compress the dynamic range of HDR images (videos).

Perceptual Experience Analysis for Tone-mapped HDR Videos based on EEG and Peripheral Physiological Signals [PDF]
S.-E. Moon and J.-S. Lee, "Perceptual Experience Analysis for
Tone-mapped HDR Videos Based on EEG and Peripheral Physiological Signals," in
IEEE Transactions on Autonomous Mental Development, vol. 7, no. 3, pp.
236-247, Sept. 2015, 2018 High dynamic range (HDR) imaging has been attracting much attention as a technology that can provide immersive experience. Its ultimate goal is to provide better quality of experience (QoE) via enhanced contrast. In this paper, we analyze perceptual experience of tone-mapped HDR videos both explicitly by conducting a subjective questionnaire assessment

Journal of the International Phonetic Association, 2014 In this work, Mandarin tone production is examined using simultaneous laryngoscopy and laryngeal ultrasound (SLLUS). Laryngoscopy is used to obtain information about laryngeal state, and laryngeal ultrasound is used to quantify changes in larynx height ...

Which tone-mapping operator is the best? A comparative study of perceptual quality [PDF]
Xim Cerda-Company, C. Alejandro Parraga, and Xavier Otazu, "Which
tone-mapping operator is the best? A comparative study of perceptual
quality," J. Opt. Soc. Am. A 35, 626-638 (2018), 2016 Tone-mapping operators (TMO) are designed to generate perceptually similar low-dynamic range images from high-dynamic range ones. We studied the performance of fifteen TMOs in two psychophysical experiments where observers compared the digitally generated tone-mapped images to their corresponding physical scenes.

Human Cardiovascular Adjustments to Rapid Changes in Skin Temperature during Exercise
Circulation Research, 1969 In 11 normal men, central circulatory responses were measured while skin temperature was changed in a square-wave pattern during uninterrupted exercise (26% to 64% maximal oxygen consumption).
