High Dynamic Range Mapping for Synthetic Aperture Radar Images

open access: yesTelfor Journal, 2018
Luminance compression is often performed for high dynamic range images (still images and videos). A nonlinear tone mapping is applied for the compression in order to reproduce high dynamic range images using devices with a more limited (low) dynamic ...

Focus and tone [PDF]

open access: yes, 2008
Tone is a distinctive feature of the lexemes in tone languages. The information-structural category focus is usually marked by syntactic and morphological means in these languages, but sometimes also by intonation strategies.

Hierarchical tone mapping based on image colour appearance model

open access: yesIET Computer Vision, 2014
To solve the problem of low efficiency and poor effect of the current tone mapping methods for the high dynamic range images, the authors propose a hierarchical tone mapping algorithm based on colour appearance model. The discrete Gaussian kernel is used

Hardware Implementation of an Automatic Rendering Tone Mapping Algorithm for a Wide Dynamic Range Display

open access: yesJournal of Low Power Electronics and Applications, 2013
Tone mapping algorithms are used to adapt captured wide dynamic range (WDR) scenes to the limited dynamic range of available display devices. Although there are several tone mapping algorithms available, most of them require manual tuning of their ...

Identification of the formation of resonant tones in compressible cavity flows [PDF]

open access: yesAerospace Science and Technology, 2018
Abstract Identification of the fluid dynamic mechanisms responsible for the formation of resonant tones in a cavity flow is challenging. Time-frequency non-linear analysis techniques were applied to the post-processing of pressure signals recorded on the floor of a rectangular cavity at a transonic Mach number.

Experimental study of locally loaded timber in compression perpendicular to the grain [PDF]

open access: yes, 2011
Since the test method for compression strength perpendicular to the grain was changed from a partial area to a full area loading test, strength values for softwood in EN 338 were significantly reduced.

Enriched sensory feedback delivered during a voluntary action boosts subjective time compression

open access: yesFrontiers in Psychology, 2023
IntroductionThe subjective experience of time can be influenced by various factors including voluntary actions. In our previous study, we found that the subjective time experience of an action outcome can be compressed when an individual performs a ...
