Two images with identical depth of field may have significantly different bokeh, as this depends on the shape of the lens diaphragm. In reality, the circle of confusion is usually not actually a circle, but is only approximated as such when it is very small. When it becomes large, most ...
A unique bifocal compound eye visual system found in the now extinct trilobite, Dalmanitina socialis, may enable them to be sensitive to the light-field information and simultaneously perceive both close and distant objects in the environment. Here, insp
On a night where there was plenty of attention to who would start at quarterback, it was Kansas’ backfield that helped steer the ship. All four running backs who played on Friday (Neal, Daniel Hishaw Jr., Dylan McDuffie and Sevion Morrison) ultimately recorded a touchdown in ...
Moreover, in actual surgery, the accuracy of reconstruction may be significantly deteriorated because the entire surgical field is constantly changing due to the autonomous movement of an organ itself and the deformation of an organ due to contact with surgical instruments such as forceps. Therefore,...
In the computer vision field, human action recognition (HAR) has gained a great importance in recent years, mainly due to its multiple applications in the study of human behavior, safety or video surveillance, which has attracted the attention of many researchers [5,31,52,75,86]. ...
Depth of field is determined by three factors – aperture size, distance from the lens, and the focal length of the lens. Let’s look at how each one works.

The success of new 3D services is a reality due to the increase of quality of experience. Although there are some factors and initial measurement devices in this field, there are still no common way and procedure to compare 3D video contents and integrated solutions and obtain an evaluation of...
of the camera driven at maximum of 25 fps. The computer vision and engineering community have described a number of algorithms for defocus computation32,33,34. However, they typically require multiple concurrent images35,36,37, lightfield systems38, specific lens apertures35,39, correlations40, ...
While metagenomic sequencing has become the tool of preference to study host-associated microbial communities, downstream analyses and clinical interpretation of microbiome data remains challenging due to the sparsity and compositionality of sequence mat
