Human Visual System Model-Based Optimized Tone Mapping of High Dynamic Range Images

open access: yesIEEE Access, 2021
High dynamic range (HDR) image and video technology can provide significant picture quality improvement over the standard dynamic range (SDR). However, when HDR content is represented on an SDR display, dynamic range compression may result in image ...

Application of Pulse Compression Technique in High-Temperature Carbon Steel Forgings Crack Detection with Angled SV-Wave EMATs

open access: yesSensors, 2023
In order to solve the difficulty in localization and poor signal-to-noise ratio (SNR) of the angled shear vertical wave (SV wave) electromagnetic acoustic transducer (EMAT) in cracks detection of high-temperature carbon steel forgings, a finite element ...

Tone-Mapping Using Perceptual-Quantizer and Image Histogram

open access: yesIEEE Access, 2020
A new tone-mapping algorithm is presented for visualization of high dynamic range (HDR) images on low dynamic range (LDR) displays. In the first step, the real-world pixel intensities of the HDR image are transformed to a perceptual domain using the ...

The effect of compression of the aorta on the tone of the uterus

open access: yesKazan medical journal, 2021
Mikulicz Radecki and Lu eg (Zentr. F. Gyn., 1924, No. 21) by experiments on animals (rabbits) were convinced that pressing the aorta only at the beginning, due to the depletion of the uterus with oxygen (resp. Carbon dioxide overload), causes contraction of the uterine muscles, in the future but it is replaced by atony.

The Development of a Single Frequency Place in the Mammalian Cochlea: The Cochlear Resonance in the Mustached Bat Pteronotus parnellii [PDF]

open access: yes, 2003
Cochlear microphonic potentials (CMs) were recorded from the sharply tuned, strongly resonant auditory foveae of 1- to 5-week-old mustached bats that were anesthetized with Rompun and Ketavet.

A Crack Size Quantification Method Using High-Resolution Lamb Waves

open access: yesSensors, 2021
Traditional tone burst excitation cannot attain a high output resolution, due to the time duration. The received signal is much longer than that of excitation during the propagation, which can increase the difficulty of signal processing, and reduce the ...
